Product Identity

The Yale 4705LN is a Grade 1 cylindrical lockset built for commercial storeroom doors. It uses an SFIC-prepped chassis in the 4700LN Augusta style with a 626 dull chrome finish. Heavy-gauge steel construction meets ANSI/BHMA A 156.2 Grade 1, ADA, UL and cUL listings, plus a three-hour fire rating. This lock is not for residential entry sets that need a thumb-turn or push-button privacy function.

Supplied Configuration

The lock ships less SFIC cylinder, so the core must be sourced separately to match an existing key system. A 2-3/4 in. backset and a 2-1/4 x 4-7/8 in. strike are included, while the rose measures 3-1/2 in. in diameter. No cylinder, keys or core-control tools are bundled, so facilities teams must plan for separate cylinder procurement.

Installation Notes

The lock fits doors 1-3/8 in. to 1-3/4 in. thick with standard cylindrical prep. Right-angle lever orientation is fixed, so handing must be confirmed before mounting. Common issues arise when the SFIC core length does not match the housing depth or when the strike lip conflicts with the frame rabbet.

Questions about this item

Will the SFIC cylinder need replacing separately from the lock body?

The lock is supplied less SFIC cylinder so you will need to fit a compatible SFIC core before use; the cylindrical chassis itself is Grade 1 heavy-gauge steel and does not require scheduled replacement.

What stops the latch from retracting when the lever is abused under constant traffic?

The storeroom function keeps the outside lever rigid at all times — only a key in the SFIC cylinder retracts the latch, so lever torque cannot override the mechanism.

How much heat does the lock generate during continuous daily operation?

As a purely mechanical Grade 1 cylindrical lock it produces no measurable heat; the dull-chrome 626 finish and steel components remain at ambient temperature regardless of cycle count.
