48H SERIES MORTISE DEADLOCKS

40H SERIES - FEATURES
1. Solid one-piece stainless steel anti-friction latch provides 50% more surfacecontact with strike for superior strength and security. Reversible latch rotates 180 degrees for easy handing change without opening case.
Precision-engineered curve provides enhanced cycle life with reduced wear to the strike.
2. Non-handed cylinder retainer.
3. Armored front completely surrounds latch and deadbolt providing increased lateral strength. Staked assembly design allows the armored front to selfalign with the door bevel during installation.

5. Roller bearing hub mechanism provides smooth, wear resistant operation.
6. Locking toggle includes clear indication of “locked” and “unlocked” states. 7. 40H case, cover, and armored front manufactured from 0.095” cold rolled steel for strength and durability.

9. Four position hub toggle design determines whether each hub is always locked, always unlocked, or locked by key for easy handing change without opening case.
10. Lever return spring mechanism located in trim for enhanced protection against lever droop, providing a firm, positive return of the lever to the horizontal position.
11. Self-aligning trim mechanism for fast, easy, and accurate installation.
12. Curved lip strike and strike box assembly provides an aesthetic, non-handed solution to complement field reversible case.
13. Solid machined cylinder rings with wavy washer provides resistance to wrenching of cylinder. Cylinder security screw prevents removal of cylinder without first removing interchangeable core.

BEST 48H7M626 – Frequently Asked Questions

1) What is the Best 48H Standard Series mortise deadlock used for?
The Best 48H provides high-security deadlocking in commercial and institutional applications. Double cylinder function requires key operation from both sides. Common in office buildings, schools, and secure facilities where controlled access is critical.
2) What door thickness does this mortise lock fit?
Standard mortise locks typically fit 1-3/4" doors. Verify your door thickness and mortise pocket dimensions before ordering. Check manufacturer template for exact cutout specifications.
3) How do I determine left or right hand for installation?
Stand on the side where the door opens toward you. If hinges are on your right, it's right hand. If hinges are on your left, it's left hand. Most mortise locks are field reversible.
4) What finishes are available for the Best 48H series?
Best offers multiple finishes including satin chrome, bright brass, and oil rubbed bronze. Finish availability varies by model. Contact us to confirm specific finish options for this lock body.
5) What security grade does this lock meet?
Best Standard Series locks are designed for commercial duty. The 7-pin housing provides enhanced security over standard 5-pin systems. Verify specific ANSI grade requirements for your application.
6) Does this lock meet fire door code requirements?
Double cylinder locks may not be suitable for fire egress doors due to code restrictions. Check local fire codes and AHJ requirements. Consider single cylinder or classroom function for fire-rated openings.
7) What cylinders and cores work with this housing?
Accepts all Best interchangeable cores and standard mortise cylinders. The 7-pin housing accommodates extended pin configurations. Browse our Best lock cylinders and cores for compatible options.
8) What tools do I need for installation?
Installation requires mortise lock jig, hole saw, chisel set, and drill bits. Follow manufacturer template precisely. Pre-existing mortise pockets may need adjustment for proper fit.
9) How do I adjust the latch and deadbolt?
Most adjustments involve strike plate alignment and latch projection. Deadbolt throw should extend fully into strike. Lubricate mechanism with graphite, never oil-based lubricants.
10) Are there other Best 48 series functions available?
Best offers multiple functions in the 48 series including classroom, storeroom, and passage functions. Each serves different security and access needs. Check our door hardware selection for alternatives.
11) Will this work in high-traffic environments?
Best Standard Series handles moderate to heavy commercial use. For extreme high-traffic applications, consider Best's heavy-duty series. Regular maintenance extends service life in demanding conditions.
12) What are the key measurements I need to verify?
Measure door thickness, backset distance, mortise pocket depth and width. Standard backset is 2-3/4". Verify strike plate alignment and door frame clearances before installation.
