L-type post holders are sized for common square timber posts such as 70x70, 90x90 and 100x100 mm, which bolt onto the upright leg of the L. Match the plate width to your post section and use the pre-drilled holes to fix the post with coach bolts or screws.

An L-type post holder is fixed either by concreting the foot into a footing or by bolting the base plate to an existing concrete slab or foundation. The post is then bolted to the vertical leg, keeping the timber off the ground to reduce rot, a more permanent method than a drive-in spike.

L-type post holders are manufactured from hot-dip galvanised steel, giving a zinc coating that resists rust in outdoor and in-concrete conditions. Keeping the post base off the ground also reduces timber contact with soil moisture, helping the post last longer.

An L-type post holder set in concrete provides a strong, rigid base for fence, gate and structural posts, resisting uplift and lateral movement through its bolted connection. For higher loads, choose a heavier-gauge holder and a deeper concrete footing, and bolt through every fixing hole.
