Overview

About this product

Hager's 3857S puts the intruder classroom with deadbolt function (F33) in a 3800 Series Grade 1 mortise lock with Withnell levers on sectional (rose) trim. The round rose gives a smaller footprint on the door face. Use it on classrooms and staff rooms that lock by key from inside the room.

Finish choices are 10B, 26D, 32D and BLK, and the backset is 2-3/4". The lock meets ANSI A156.13 Grade 1, Series 1000 Operational and Security. On the sectional trim the cylinder sits in its own collar beside the lever rose. Choose a conventional Schlage C keyway cylinder, an SFIC 7-pin or LFIC 6-pin prep less core, or less cylinder to match your key system.

What the function does

Intruder classroom lock with deadbolt. Both levers retract the latchbolt. The deadbolt is thrown or retracted by key from inside or outside, and throwing it locks the outside lever. Turning the inside lever retracts both bolts together and unlocks the outside lever.

Highlights

  • Deadbolt locked by key from either side
  • No inside thumbturn
  • Throwing the deadbolt locks the outside lever
  • Inside lever retracts both bolts together
  • Sectional rose trim with Withnell lever
  • ANSI A156.13 Grade 1, Series 1000
  • 2-3/4" backset; finishes 10B, 26D, 32D and BLK

Common questions

Can a teacher lock the door without stepping into the hallway?

Yes. The deadbolt can be thrown by key from the inside, which also locks the outside lever.

Is there a thumbturn on the inside?

No. The deadbolt on this function is operated by key from either side.

What is sectional trim?

Sectional trim mounts the lever on a round rose instead of a full plate, with the cylinder in its own separate collar.

Which cylinder options are there?

Conventional cylinder in the Schlage C keyway, SFIC 7-pin prep less core, LFIC 6-pin prep less core, or less cylinder.

What backset does it use?

The backset is 2-3/4".
