Additional Information

Not Included in this Kit

Wood - Lumber is a) very expensive to ship and b) readily available to most people at local home improvement and building supply stores. By buying your wood locally, you also have more options on the exact type of wood you'd like that is appropriate for your area's climate.

Anchoring Hardware - While this pergola kit does include stainless steel wood screws for securing 4x4" wood posts into the brackets, it does not include anchoring hardware for securing the base brackets into a secure base (i.e. cement pad, deck, landscape toppers, concrete footing, etc.). This is because the anchoring hardware you need will vary based on a) what type of material you're going into and b) local building codes.

Required Lumber & Estimated Cost

As noted above, wood (lumber) is NOT included in this pergola bracket kit (nor is the hardware you'll need to anchor the base brackets).

Before you can build your pergola, you'll need to purchase the following items from a local building supply store or lumber yard:

- Nine (9) 8' long 4x4 posts
- Twelve (12) 10' long 4x4 posts
- If you select a roof... Sixteen to sixty-four (16-64) 10' long 2x4 slats *OR* twelve to twenty-eight (12-28) 10' long 4x4 posts - dependent upon your roof selection
- Anchoring hardware (36 pieces)

The estimated cost for the above lumber and anchoring hardware is $747 - $1457 (depending on the roof you choose) OR $645 if you purchase the frame only (no roof).

Together with the cost of this Zen Pergolas bracket kit, the estimated TOTAL ALL-IN COST for your pergola is $2106 - $3992 depending on your roof selection (or $1644 for the frame only). This is only an estimate... actual costs will vary depending on the type of wood you buy, your location, local stores & availability, and various other factors.

Please note that the images above show a 24' x 24' pergola (not a 20' wide x 20' deep pergola for which the kit on this page is intended). The number of roof rafters/slats will differ from what is pictured above since this kit's roof is only intended to cover the pergola's 20-foot depth (not a 24' depth). That said, the spacing between rafters/slats will be very similar to what is shown in these images.

Well Made.

Well made product and works well holding 6x6 posts in place. The only thing I would recommend would be holes in bottom for drainage.

Hey Brian, thank you for the great review and thank you for the feedback. We've received this feedback from others in the past and it's something that we're working on implementing right now. Within a month or so all base brackets will include a hole in the base for drainage.

Great Quality

These angle braces were really heavy duty - much more-so than I expected. Also, the braces arrived very quickly. Great service
