Flex-Bow Gate Closing Bumper For 4x4 Post
This screw-on gate stop goes on a 4x4 fence post (89 mm face). It is 70 mm wide, 70 mm tall and stands 37 mm off the post. Its front is a sprung bow leaf with 6 mm of travel, so the gate stops softly in line with the latch instead of slamming and loosening the hardware. It mounts with two #10 (4.8 mm) or M5 screws through 5.5 mm counterbored holes, and its hollow body is open at both ends so rainwater drains through.
4x4 Post Mailbox Arm Knee Brace
A 125 x 125 x 28 mm triangulated knee brace that screws to the 89 mm (3.5 in) face of a 4x4 wood post and props up the underside of a 2x4 mailbox cross-arm. It replaces the rusted stamped-steel brace, so a sagging or snapped arm doesn't mean buying a whole new post kit. Each leg has two 5.5 mm holes for #10 wood screws or M5 lag screws. The holes sit outboard of the diagonal strut, so a driver can reach them straight on. The brace prints on its side, which puts the arm's load in the plane of the layers.
Gate Opener Post Pivot Bracket
A chunky replacement post-pivot bracket for a swing-gate opener arm: an 88 x 48 mm backplate that covers the full 3.5 in face of a 4x4 wood or vinyl post, four 5.5 mm holes (M5 / #10 lag screws) on a 56 x 24 mm pattern, and a 18 mm thick tongue with an 8.3 mm vertical bore for an 8 mm / M8 pivot pin 24 mm off the post face. Printed on its back so every layer line runs across the pull direction, with twin 45 degree webs tying the tongue into the plate — it replaces the cast aluminium bracket that snaps or strips out of a Mighty Mule / Ghost Controls style kit.
4x4 Post Cap String Light Hooks
A weather cap for a nominal 4x4 fence or deck post (88.9 mm actual) with a 91 mm square socket, 20 mm engagement and two M4 clearance holes so it screws down and won't blow off. Twin horns on opposite faces carry a cafe-string-light cable in an 8 mm wide, 10 mm deep slot; overall 127 x 97 x 50 mm with a hollow 50-degree pyramid roof that sheds water and prints support-free.
