Schlage B660P 626 IS-LOC – Frequently Asked Questions

1) What is the Schlage B660 deadbolt designed for?
The B660 is a Grade 1 commercial single cylinder deadbolt with inside indicator showing locked/unlocked status. Built for heavy-duty applications in offices, schools, and institutional buildings.
2) What door thickness does this deadbolt fit?
Standard B660 fits doors 1-3/8" to 1-3/4" thick. Extended versions available for thicker doors. Check manufacturer template for exact measurements.
3) How do I determine the correct handing for installation?
Stand on the side where hinges are visible. If hinges are on right, it's right-handed. If on left, it's left-handed. Most B660 models are reversible during installation.
4) What finishes are available for the B660 series?
Common finishes include satin chrome, bright brass, oil-rubbed bronze, and satin brass. Specific finish availability varies by model number. Check product specifications for exact finish code.
5) What does Grade 1 certification mean?
Grade 1 is the highest ANSI/BHMA security rating. Requires 10 cycles of 75 foot-pounds torque resistance and 1 million cycles operational testing. Suitable for high-traffic commercial applications.
6) Can this deadbolt be keyed to match existing locks?
Yes, B660 uses standard Schlage C keyway and can be keyed alike or into master key systems. Consult locksmith for keying requirements and existing system compatibility.
7) What replacement parts are commonly needed?
Common service parts include cylinder assemblies, thumbturn assemblies, and strike plates. Browse our Schlage parts section for genuine replacement components.
8) What are the basic installation requirements?
Requires 2-1/8" cross bore and 1" edge bore. Standard 2-3/4" or 2-3/8" backset. Use manufacturer template for precise hole locations. Reinforced strike plate recommended for masonry frames.
9) How do I maintain proper operation over time?
Lubricate cylinder and bolt mechanism every 6 months with graphite spray. Check strike alignment if binding occurs. Clean indicator mechanism to ensure proper locked/unlocked display.
10) What other Schlage commercial deadbolts are similar?
Consider B560 for double cylinder applications or B760 for thumbturn both sides. All share similar Grade 1 construction and mounting requirements.
11) Will this work in extreme weather conditions?
B660 meets ANSI Grade 1 environmental testing including salt spray and temperature cycling. Use appropriate finish for coastal or industrial environments. Lubrication may require adjustment in extreme climates.
