Yale Accentra AU4701LN 626 Passage Lever

This Grade 1 cylindrical lockset uses a heavy-gauge steel chassis and a dull-chrome 626 finish. The Augusta 4700LN lever style meets ANSI/BHMA A156.2 requirements and carries a three-hour fire rating. It fits doors from 1-3/8 to 1-3/4 inches thick with a 2-3/4 inch backset. Buyers who need a locking function or electronic access cannot use this passage model.

Sustained commercial traffic performance

The Grade 1 certification confirms the lockset passes cycle and torque tests far above residential grades. Heavy-gauge steel components resist wear from constant lever operation in hallways, offices or public buildings. The three-hour UL and cUL fire rating means the assembly maintains integrity during prolonged fire exposure. Installations needing a privacy or entry function must choose a different lockset.

Installation practicalities

The 2-3/4 inch backset and supplied 2-1/4 by 4-7/8 inch strike match standard commercial door prep. A 3-1/2 inch rose covers typical cylindrical cut-outs without extra drilling. The lockset ships without a cylinder, so a compatible core must be sourced separately for keyed applications. Doors outside the stated thickness range or with non-standard backsets will not align correctly.

Highlights

  • Grade 1 security for heavy commercial use
  • Passage function allows free movement both sides
  • Dull chrome finish resists wear and corrosion
  • ADA compliant lever meets accessibility standards

Questions about this item

Does the 4700LN Augusta lever generate any noise or heat during continuous daily use?

No — this is a purely mechanical passage lockset with no motor, electronics or power supply, so it produces no audible noise and no heat regardless of how often it is cycled.

What door preparation must already exist for the 4701LN 626 to install correctly?

The door needs a 2-3/4 in. backset bore, a cylindrical cross-bore for the latch, and a thickness between 1-3/8 in. and 1-3/4 in. to match the lockset’s adjustable chassis.

Will the ANSI/BHMA A156.2 Grade 1 strike plate supplied with the 626 finish align with an older mortise prep?

The included strike is a 2-1/4 x 4-7/8 in. ANSI template; it will not match a legacy mortise pocket, so the frame would need to be re-routed or a retrofit strike adapter used.
