PREMIUM SECURITY DOOR
Measure for Rough Opening Height

Page 2
Standard security door handle height is 39½". 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 38½"-40½" 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.

the measurement worksheet
and follow the instructions to
