About this product…

This Mounting Kit is a base needed in order to attach RDI’s Porch Posts to your deck or porch. There are two models offered; the standard, and the wind uplift model. The standard model is used when you have the ability to jack up your roof by 2” during installation. The wind uplift model can be installed when jacking up the roof is not an option. The standard kit mounts to the floor and roof, the weight of the roof holds the post in place. When using the wind uplift kit, the bracket is mounted to the post then slid into place and secured to the floor and the roof. The wind uplift model includes a piston lock that prevents wind uplift up to 2,800 pounds, ensuring ultimate stability.  

The mounting kit is necessary if installing with the interior aluminum structural posts; a part in RDI’s Porch Posts
