Eliminate the need for time-consuming wood post installation with Heavy Duty Structural Posts from Durables. These post mounts are available for 36 inch or 42 inch railing height and can be ordered with installation hardware for either wood or concrete installation. The post mount serves as a sturdy anchor for installing railing and it fits perfectly inside of a 4 inch vinyl post sleeve.

For wood installation, a 3/8 inch drill bit will be needed to drill pilot holes, and a 1/4 inch masonry bit is required for concrete installation.
