Used this item, worked fine, needed some trimming overall very pleased.
Jury's still out
I used Titan post anchors on a solid surface wood deck and figured the gasket kit was a great idea. There were a couple problems with the "whole kit" experience. The kit included 3/8" lag bolts to bolt the base to the deck. The post base holes were only 5/16" and the bushings for the gasket kit were 1/4". I used 1/4" bolts which held the railing solid. A seal was difficult to obtain due to the sloping deck for drainage. Only one side of hold down bolts were tight to the gasket. the remaining edges were shimmed up to plumb the post. It was difficult enough to set the base over the bushings without trying to stack washers on them- the solution suggested for a shimmed post. Time will tell if I need to deal with a leaking deck.
