Frequently Asked Questions

What makes the KT Series extra heavy duty?
The KT bolt contains two concealed 1/4" case-hardened steel roll pins for added resistance to sawing and drilling attacks beyond PDQ's other deadbolt duty tiers. It pairs this with a wrought brass scalp and reinforced zinc diecast rose.

When should a KT deadbolt be specified instead of a KM or KV?
The KT is intended for extra heavy duty, high-abuse exterior doors, high-vandalism areas and facilities needing maximum forced-entry resistance. The KM is built for standard heavy duty commercial exterior doors and the KV for lighter-duty interior or light commercial use.

What door thickness and backset does the KT fit?
The KT is built for standard 1-3/4" doors with a 2-1/8" diameter door prep and supports a 2-3/4" (default) or 2-3/8" backset. Other door thicknesses are available by contacting the factory.
