These 4x4 pergola brackets fit nominal 4x4 lumber, which actually measures about 3.5 x 3.5 inches. Each kit pairs galvanized steel brackets with screws and expansion bolts. You supply the posts, beams and roof or shade cover.

4x4 is the widest choice of layouts at Jurrque: it is the only post size for wall-mount, sloped-roof and A-type kits, and it is also offered for the 4-post, 6-post and extension kits.

Before You Order 4x4 Brackets

  • Measure your posts. Standard 4x4 lumber measures about 3.5 in. per side. Rough-sawn or full-dimension posts can be larger, so check them before ordering.
  • Keep every part the same size. 4x4 and 6x6 hardware is not interchangeable, so order an extension kit in 4x4 if your 6-post kit is 4x4.
  • Thicker posts? The 4-post, 6-post and extension kits also come in a 6x6 version. Compare 6x6 pergola brackets.
  • Not sure which layout fits? See every layout side by side in DIY pergola kits.

4x4 Pergola Bracket Questions

What size is a 4x4 post really?

About 3.5 x 3.5 inches. 4x4 is the nominal lumber size, and Jurrque 4x4 brackets are made for those actual dimensions.

Do 4x4 pergola bracket kits include the wood?

No. Kits include galvanized steel brackets plus screws and expansion bolts. Posts, beams, roof panels and shade fabric are sold separately.

Which Jurrque kits come in 4x4 only?

The wall mount, double wall mount, sloped roof, double sloped roof and A-type kits. The 4-post, 6-post and extension kits come in both 4x4 and 6x6.

Can I mix 4x4 and 6x6 hardware?

No. The two sizes are not interchangeable. Order every kit for one pergola, including an extension kit, in the same post size.
