List of Recommended Tools

Measuring Tape

A tape measure in good condition with a capacity to measure at least 16 feet (5 m) is required.

Hammer

A framing hammer with, at least, a 16 oz head is required to hammer in concrete bull anchors into concrete pads and concrete footings.

Framing Level

A framing level, 4 feet long, is recommended to check plumb of posts and level of headers and ridge rafters.

Ratchet  & Socket Drivers

A racket  & socket drivers are recommended to fully drive lag screws.

7/16″ Hex Socket

The 1/4″ x 1-1/4″ Lag Screws have a 7/16″ hex head. A 7/16″ Socket is required to drive the 7/16″ head lag screws.

9/16″ Hex Socket

The 3/8″ x 3″ Lag Screws used for raftered pergola brackets have a 3/8″ hex head. A 9/16″ Socket is required to drive the 3/8″ head lag screws.

3/32″ Drill Bit

A 3/32″ pilot hole is required if driving 1/4″ diameter lag screws into lumber.

Before driving 1/4″ diameter lag screws into lumber, a 3/32″ pilot hole, hole depth equal to length of screw, must be drilled to prevent the wood from cracking and to allow full lag screw penetration.

11/64″ Drill Bit

An 11/64″ pilot hole is required if driving 3/8″ diameter lag screws lumber.

Before driving 3/8″ diameter lag screws into lumber, an 11/64″” pilot hole, hole depth equal to length of screw,  must be drilled to prevent the wood from cracking and to allow full lag screw penetration.

1/2″ x 4″ Masonry Drill Bit

1/2″ diameter x 2-3/4″ concrete bull anchor bolts are included with floor anchor brackets. These anchors are to be employed to secure floor anchor brackets to concrete pads and concrete footings.

Use the 1/2″ x 4″ masonry drill bit to drill 1/2″ x 2-1/4″ deep holes in concrete pads and concrete footings.

Hammer Drill

A hammer drill (electric drill with optional hammer mode) is required to predrill holes in concrete pads, concrete footings, and masonry walls before proper anchor hardware are installed to secure floor anchor brackets or wall anchor brackets.

10″ Compound Miter Saw

A 10″ compound miter saw is recommended for making straight, angled, and compound angled cuts as required.  A 10″ sized saw will have the capability to cut compound angles in lumber members up to 2x8s. 

Alternatively, a sliding compound miter saw can be used as a better alternative. Sliding compound miter saws have the capability to cut lumber members up to 2x12s and beyond.

Lumber Information

Lumber Types

  • The wood species you select will be dependent on your personal preference, budget, and your tolerance to future maintenance needs.
  • For lumber exposed to sunlight and weather conditions, select pressure treated pine, cedar, or redwood.
  • For lumber shielded from exposure to sunlight and weather (roof rafters and roof crosstie beams) you may select from kiln dried pine, cedar, or redwood, depending on your budget and cosmetic preference.
  • For low budget and low maintenance for solid roofed structures, we recommend cedar posts, cedar roof skirts, and kiln dried pine rafters and crosstie beams.

Selecting lumber members at the lumberyard

  • Due to manufacturing processes intolerance, delivered lumber lengths can vary.
  • The length of lumber delivered to stores can be longer than the labeled length but will never be less than the labeled length dimension.
  • We suggest that you measure each lumber member before adding to your cart at the store.
  • If available, select lumber members which are slightly longer than the labeled length. Example: if buying 96” length 4x4s. Measure and select member which exceed 96”.
  • Some pieces can have lengths as long as 96-3/8”. The extra length will provide flexibility if you need to trim the ends for squaring or cleaning purpose

Plan ahead to save money and to minimize wood waste

We provide detailed information for you to plan your project. Use the information wisely and make wise judgements about the header lengths which directly drive the overall pergola size.

Example: if you decide to use 60” (1524 mm) length headers, instead of buying 96” (2438 mm) lumber and cutting off and discarding 36” (914 mm), you may be able to buy 120” (3048 mm) long 4x4s and yield two 60” (1524 mm) lengths. If you need a 72” long lumber member, you may be able to acquire an 84” long lumber and trim off only 12”. Check with local lumber yards for available lengths of lumber and plan accordingly.

Octagon Pergola Size

Octagon Sizes

We have designed our products to allow creation of unlimited sizes of Octagon shapes in widths ranging between 8 ft (2,438 mm.) and 20 ft (6,096 mm.). Although an Octagon shape as small as 8 ft wide is possible, we do not recommend Octagons in sizes smaller than 12 feet. This because Octagon Shapes do not appear attractive when too small. There will be too many vertical posts in close proximity and hinder your movement in and out easily.

Instead, for sizes smaller than 12 feet, consider our Hexagon shaped products. Hexagon shapes appear cosmetically attractive in small sizes. See this link for our Hexagon Collection offerings:  https://riooutdoors.com/hexagon-solid-roof-collection/

If available space allows, consider a minimum Octagon width of 12 feet. Larger Octagons are cosmetically attractive.

The size of octagons are defined by DIM A (width) and DIM B (depth). As the Header Length A increases, the width of the Octagon, DIM A, increases, accordingly. The steel brackets remain unchanged, only the header lengths increase as the octagon width increases.

As long as you adhere to common building practices and building structural strength requirements for open horizontal spans as allowed by your local building codes, you can vary the size of your custom structure as you wish. Just remember to limit the span of the lumber members within limits specified by your local building codes. This is especially important for the roof rafter member size and cross-tie member size in areas where snowload is a concern.

Just remember that our brackets make the lumber joints “super strong”. But the lumber, itself, is the structural item that limits the open spans.

Full Octagon Sizes

The size of the octagon shape is determined by the overall width of the octagon shape. The size of the octagon shape you can create using our brackets ranges between 10 ft (3,05 m) and 20 ft (6.1 m).

[Larger sizes than 20 ft (6.1 m) are available with special consideration. Please contact us directly for special requirements for larger sizes than specified here.]

The Header Length A is the primary driving factor which determines the octagon dimensions.

Note that DIM A and DIM B are equal and are measured between two parallel sides of the octagon.

DIM A defines the width of the octagon. Refer to Table 1, below.

If you desire a 12 ft. (3.66 m) wide octagon, select the row in column [Width (ft.) DIM A] that contains the dimension 12 ft. (3.66 m). 

The header length  in the same row equals 56 11/16” (1440 mm) for 4×4 size and 55 3/16″ (1402 mm) for 6×6 size.

You will cut and prepare eight headers, all with their lengths equal to this header length (either 4×4 or 6×6 specific).

See header A preparation details here.

Table 1: Full Octagon Dimensions

Partial Octagon Sizes

The lengths of headers, marked A and B ,determine the width and depth of partial octagons.

Length of header A  determines width dimension (DIM A) of the partial octagon.

A combination of lengths of headers A and B define the depth dimension (DIM B) of the partial octagon.

Refer to Tables 2 and 3, below.

Headers marked A and B can have almost equal lengths, with variance in length only due to the cut angle difference on one end of Header B. Tables 2 and 3, below, assume that the lengths of headers marked A and B are almost equal.

See header A preparation details here.

See header B preparation details here.

Floor Anchor Types

RioOutdoors.com offers two floor anchor types to suit your specific need.

Surface Mount Anchor type

  • The Surface Mount anchor type employs floor anchor brackets (4×4, Floor Anchor Bracket or 6×6, Floor Anchor Bracket ) to secure the structure posts on top of a concrete pad, concrete footings, or an existing deck.
  • Use the Surface Mount anchor type if you have an existing concrete pad or deck, or you plan to add a new concrete pad or new concrete footings.
  • The floor anchor brackets (4×4, Floor Anchor Bracket or 6×6, Floor Anchor Bracket ) are secured to concrete pads or concrete footings using four ½” X 2-3/4” Bull Concrete Anchors, included with the brackets.
  • The posts slide inside the floor anchor brackets and are secure using four lag screws, included with the brackets.

Floating Deck Anchor type

  • The floating deck anchor type employs floating footing lumber members connected together at all corners to elbow brackets to form an outer floating wood structure on top of level and solid ground or on top of an existing concrete pad.
  • Use the floating deck anchor type in the absence of a concrete pad or on top of an existing concrete pad.
  • The floating footer members can be secure to the ground by drilling ½” vertical holes through the floating footer lumber members and driving 4 ft. ½” steel rebars into the ground.
  • To secure the floating footer lumber members to an existing concrete pad, obtain appropriate concrete anchors, locally, and secure to the concrete pad as instructed by the concrete anchor manufacturer.

Maintenance

Maintenance Information
  • The joinery brackets supplied by RioOutdoors.com do not require any maintenance. All brackets are coated with durable powder paint for rust-proofing.
  • The lumber members of the solid roof structure (rafters, cross tie beams, post top headers) do not require any maintenance because they are shielded permanently from sunlight and weather.
  • Other lumber members which are exposed to sunlight and weather, however, may require periodic maintanence depending on the type of lumber you selected and the type of sealant or paint you applied.
Adding vinyl sleeve protection
  • Various vinyl sleeves are available in the market which are designed to wrap around wood members. You may choose to add vinyl sleeves around posts to protect the post lumber members and eliminate future maintenance work. Just remember that vinyl sleeves must be installed during initial installation around the post lumber members and trimmed to the steel post-end brackets. The steel brackets are not designed to accept the extra thickness of the vinyl sleeves.
Lumber Maintenance
  • Maintenance requirements for lumber depends on the wood species used and the extent of sun and weather exposure to the lumber.
  • Cedar and redwood lumber require less maintenance due to their natural resistance to sun and weather.
  • Pressure treated pine is very resistant to rotting but discolors rapidly when exposed to sun and weather, thus requiring frequent resealing or painting.
