Imperial GAL-1170L- R -626 Standard Duty Classroom Entry Lever Set - Satin Chrome

The Imperial GAL-1170L-R-626 is a standard-duty classroom lever set built for schools and institutional doors at a value price. The classroom function (ANSI F84) is purpose-built for the classroom door: the outside lever is locked and unlocked by key from the outside, while the inside lever is always unlocked for free exit. A teacher controls the door with a key from the corridor, and no one inside can ever be locked in, which is exactly the behavior a classroom needs. The 1170L is non-handed and reversible, ADA compliant, and finished in satin chrome (US26D), with a lifetime mechanical warranty behind it.

How the classroom function works

This is the heart of why you'd choose the 1170L, so it's worth being precise. With the classroom function, the outside lever is controlled by key only: turn the key to lock the outside lever so the door is secured against entry, turn it back to unlock. The inside lever always retracts the latch, so anyone in the room can exit freely at any time, which is the core life-safety requirement. There's no button or thumbturn to fumble with, the locking is done from the hallway by key.

That key-from-outside control is the traditional classroom behavior: a teacher can lock the door from the corridor (including during a lockdown) without stepping inside, and occupants are never trapped. For classrooms, labs, training rooms, and any supervised space that needs keyed exterior control with guaranteed free egress, this is the right function.

Value-grade durability and security

The 1170L is a standard-duty Grade 2 leverset, the right level for commercial doors in normal traffic that don't need heavy-duty Grade 1 hardware. Despite the value price, it includes features you don't always see at this level. The lever uses a vandal-resistant free-wheeling clutch mechanism: if someone forces or hangs on the locked outside lever, the lever rotates freely instead of transferring force to the internal mechanism, which protects the lock from damage and extends its life. It's ADA compliant for accessible operation, and it's backed by a lifetime mechanical warranty and a 10-year finish warranty.

The latch is stainless steel with a 5/8" projection and a 3-hour UL fire rating, suitable for rated openings, and the thru-bolted installation (5/16" holes outside the 2-1/8" bore) adds anti-rotation security with removable thrubolts for serviceability.

Retrofits standard prep, keys to Schlage C

The 1170L is built for easy installation and keying. The 2-1/8" bore retrofits all standard cylindrical locksets, so it drops into existing door prep with a 2-3/4" backset and fits doors 1-3/8" to 1-7/8" thick (adjustable). It comes with a Schlage C keyway 6-pin cylinder and two nickel-plated keys, and it's available keyed alike or master keyed in addition to standard keyed. Because it uses the common Schlage C keyway, it keys into many existing systems, convenient for a school or facility standardizing on that keyway.

Why choose the Imperial GAL-1170L-R

Imperial (Global) builds value-focused commercial hardware, and the GAL-1170L is a lot of classroom lock for the price. You get the correct classroom-security function (keyed exterior control, free interior egress), a vandal-resistant free-wheeling clutch that protects the lock from abuse, ADA compliance, a 3-hour fire-rated latch, Schlage C keying that retrofits standard prep, and a lifetime mechanical warranty. For schools and budget-conscious institutional projects that still need a real classroom function and durable operation, the 1170L is a smart, practical choice.

One thing to confirm before ordering: the 1170L is the classroom function (F84, key locks the outside lever from outside). If you need a different behavior, Imperial's lever line also offers passage, privacy, entry, and storeroom functions. Choose keyed alike or master keyed if you need multiple locks on one key or on your building system.
