Residential and commercial security

This double cylinder deadbolt is designed for residential and commercial doors that require keyed entry on both sides. It carries ANSI Grade 1 certification and UL 437 listing for high-security applications. The Original 006 keyway provides patented key control and two keys are included with an ID card.

Resistance to sustained attack

The lock is built from solid brass and steel to withstand drill, wrench, ice pick and prying attempts over extended periods. Its Grade 1 rating confirms durability through repeated heavy-duty cycles. The adjustable backset fits door recesses of 2-3/8" to 2-3/4" without modification.

Fire-door compatibility and finish

UL listing allows installation on fire-rated doors where codes require it. The Antique Brass 09 (US5) finish resists corrosion and wear in normal indoor and outdoor exposure. No electronic components are present, so power draw and noise are not applicable.

Questions about this item

Does the Antique Brass finish on the HD2-09-006 show heat discoloration after prolonged exposure to sunlight?

The Antique Brass 09 (US5) finish is a solid brass surface that resists UV fading and will not discolour from daily sun exposure.

What door preparation is required before installing this double cylinder deadbolt?

You need a door thickness between 1-3/8" and 1-3/4" with a standard 2-1/8" cross bore and a 1" edge bore, plus the adjustable backset set to either 2-3/8" or 2-3/4" to match your existing latch hole.

Can the Original 006 keyway on this lock be rekeyed to match my existing Mul-T-Lock cylinders?

Yes, the patented Original 006 keyway allows a locksmith to rekey the cylinder so it operates with the same keys as your other Mul-T-Lock hardware.
