The PRO MaxSeal is Security Boss's top-tier insulated patio insert for sliding glass doors: no cutting, no screws. It stands in your slider's track with a dual-pane thermal glass panel and the PRO hinged dual-flap MaxSeal pet door built in, so you can take it out and use your full door opening whenever you want. Security Boss builds each insert by hand, to order, in the USA.

How it fits your slider
-
Adjustment Range is the height of your sliding door opening: Range 1 is 70" to 77.25", Range 2 77.25" to 84.5", Range 3 84.5" to 91.75", Range 4 91.75" to 99". Enter your exact opening height when you order.
- The spring-loaded top section looks like an "H" from the side, is 11/16" wide and adjusts 3.25". It can straddle a top-track center rail 9/16" wide or narrower.
- The bottom is 5/16" wide with a "C" channel that straddles the center rail in your floor track. If that rail is wider than 5/16", the insert may not fit.
-
Step Over Rise sets how high the opening sits: 2" rise is 3 3/4" off the bottom of the unit, 4" is 5 3/4", 6" is 7 3/4" and 8" is 9 3/4".
