The height adjustment range is 78¹/₂"  - 81". This range is adjusted with two extension pieces--one at the top and one at the bottom--which fit over the main framing. These each may be adjusted upward or downward and each is fixed in placed with two sheet metal screws. The user drills these holes to properly position the screws.

The flap is a heavy duty, durable black rubber. The locking cover is white enameled fiberboard which may be placed on either side. It should be used on the same side as the dog. Glass is ¹/₈" clear tempered. The flap is two-part:  A center flap and a "U" shaped gasket piece made of the same material that overlaps the flap and the frame on one side. In one direction the "U" shaped piece is pushed open with the flap. In the other direction, the "U" shaped piece remains stationary and the pet steps through it. So the opening is larger in one direction that the other. We show the smaller of the two below.  Another note:  The Pride flap is very similar to the Johnson flap except for the material it's made from.

Notice in particular that Pride offers the broadest array of colors and a consistent 4" rise in all sizes. Also, please note that the Pride patio panel does not include center post weather strip ("draft stopper"). We think you'll want this and have included it as a 'cross sell' option in our shopping cart. The sides of the panel are fully weather-stripped out of the box with a nice, black rubber weather strip.

Locking of the sliding glass door against the Pride panel is done with an included pin lock which is very effective.

Frame thickness is ³/₈" except at the height adjustments very top and very bottom which are ¹/₂" thick.
