Measurement Guide

Standard security door handle height is 39-1/2". To check for potential interference with
your main entry door handle, measure from the threshold to the center of the handle (Y). A
measurement within 38-1/2"-40-1/2" inches may result in interference. To ensure you avoid
interference issues in this instance, you may:
• Mount your security door with an opposite swing
• Order 54" handle height
• Build out the trim on your mounting surface to create clearance
Note: Paddle style handles feature a prole less likely to cause interference than knob style
handles… if measurements indicate you may be close to an interference issue, keep this in
mind when selecting your security door handle set.

Measure for Rough
Opening Width
Measure for the rough
opening you identified
in Step 2 (Figures 1-5).
Measure the top, middle
and the bottom of the door
opening. The smallest of the
three measurements will be
your rough opening width.
Enter that measurement on
the measurement worksheet
and follow the instructions to
determine if a standard size
door will fit or to order the
correct custom sized door.

measurement does NOT match a standard size door, give the sales associate your rough opening
dimensions to enter in as a custom size.

* Wider rough opening measurements within the t range may require shimming or ller wood. For opening measurements outside these
ranges, custom doors provide the best t and installation.
NOTE: If a custom size is needed, to get overall frame dimensions add 2-1/2" to width and 1-1/4" to height.
