What is the difference between Flexible Bulkhead Boots and Flexible Entry Boots?
The Flexible Entry Boot (FEB) is a studded penetration seal that requires the drilling of multiple holes as well as a hole saw cut for the pipe entry. It is slightly lower in cost, and some feel that it provides a better seal since the numerous studs give more compression to the gasket. The Flexible Bulkhead Boot (FBB) only requires one hole saw cut for mounting. While slightly more expensive, we believe that the increased cost is quickly offset by the labor savings during installation. Some also feel that, since there are fewer holes, there is also less opportunity for leaks.
