Balancing act

Automatic door opener is a low-energy operator that automatically opens the door while using a floor closer to hang and close the door. The Model 2900 is ideal for doors that are too heavy to be controlled by a traditional low-energy operator and for low to moderate traffic applications where ADA accessibility is required. By using balanced pivots, the product only needs to overcome the force of the spring of the floor closer, allowing it to control the heaviest of doors. The unit is available for both offset and center-hung doors, in models to accommodate either the push or pull side of the door, and in deep-reveal and double-egress options.

Child-safe windows

Window safety lock provides a concealed-from-view alternative to child-guard bars for multifamily residential complexes. The guard lock disables the swing-in operation on tilt-and-turn windows while the window is locked. Use of a key disengages the lock function and permits the tilt-and-turn window to swing or turn in for cleaning.

School lock in

The University of California, Los Angeles, retrofitted classrooms in its historic Haines Hall with LockLink standalone electronic access-control locking system. The Computer Managed locks installed in the hall are stand-alone, battery-powered locks that can be programmed with the software. Each lock manages up to 1,000 users and provides an audit trail for the last 1,000 events. The unit may be momentarily unlocked from the outside with an approved access code or remain unlocked using a toggle-mode access code. David Kelly, UCLA locksmith, chose the system for its automatic lock and re-lock function, which allows professors to use specific access codes to enter their assigned classrooms even on the weekends.

Locked in

Grade I locksets are built with a heavy-duty mortise chassis, provide a three-hour fire rating, and meet ADA requirements for barrier-free accessibility. The ML900 and MK900 Series locksets include high-strength springs and a positive stop to eliminate unsightly sagging levers. A hardened-steel hub design prevents damage to the lock when lever handles are abused.
