About this item
The Arrow QL11-SR is a Grade 1 cylindrical entrance lever lock with the Sierra (SR) lever design in rigid lever configuration. Entrance function means the inside lever is always free for egress, and the outside lever requires a key to retract the latch. The rigid lever designation means the outside lever stays fixed in position when the lock is secured. It doesn't rotate or give way under force, which is why it's specified for doors where lever tamper resistance is required alongside standard entrance function.
It's an ASSA ABLOY manufactured product under the Arrow brand. American Locksets is an authorized Arrow dealer.
What Rigid Lever Means and When to Specify It
Arrow's QL Series offers two outside lever configurations. The freewheeling version (QL81) spins freely when the lock is locked, absorbing torque from forced lever attempts without internal damage. The rigid version (QL11-SR) holds the lever locked in position. When the lock is secured, the outside lever does not rotate.
Rigid lever is the correct specification for applications where the lever needs to feel fully locked to the user, where outside lever tamper indication matters, or where the specification document calls for a rigid outside lever function. Both the QL11 rigid and QL81 freewheeling carry the same Grade 1 certifications. The choice between them is a function specification decision, not a quality decision.
