U-Anchor for 12 x 12 cm Posts - Per piece

Are you looking for a solid anchoring for the posts of your pergola, fence, or carport on a solid surface? With these U-anchors, you can attach 12 x 12 cm posts to stone, concrete, and wood! 

U-shaped post anchor

This strong, U-shaped post holder is 5 mm thick and contains 8 mounting holes. However, you will only require 6 fasteners. This is because the upright segments are meant to be attached to the post with two large bolts. These bolts should go straight through the post and come out the other end. The width of the base is 56 mm. The width of the two upright segments is 46 mm. The post anchors are approximately 20 cm high. The mounting holes have a diameter of 11 mm. This makes them suitable for coach screws and post holder screws 10 mm thick.

Which fasteners do I need?

For the four mounting holes in the base, you can use our 10 mm thick coach screws. You can also combine these with our nylon plugs. This allows you to easily anchor the post holder in stone and concrete. To get a larger clamping range, also use washers M10. A washer also prevents coach screw from damaging the U-anchor when tightening the screw. This reduces the chance of rust developing over time.

How to install a U-anchor

First, determine the correct place of the post holder. Then mark the 4 mounting holes of the base on the ground. Next, drill four holes in the stone on concrete with our hammer drill bit. The depth of the hole depends on the length of fasteners you are using.

After drilling the holes, insert the nylon plugs. Next, place the U-anchor in the right place and fasten it with the coach screws. During tightening, the plugs will expand, anchoring your post holder firmly in the stone or concrete.
