Maximize safety and minimize machine downtime between processes—these doors stop dangerous machinery from running when they’re open, and close in just seconds with the press of a button. Compared to other machine guard doors, they’re faster, taking only two seconds to raise and lower. They also require less floor space than light curtains because they don’t require safety zones. A safety interlock switch signals your programmable logic controller (PLC) to shut off equipment as soon as the door starts to open. Once the door is fully closed, it sends a signal to restart your machine. They have two photocell sensors for full safety coverage. If interrupted, the door will stop and reverse to the fully open position. Unlike light curtains, these doors function as a physical barrier between hazardous equipment and personnel. They’re made of vinyl fabric to keep projectiles, fluid splatter, sparks, and other machine hazards contained.

Combine these doors with machine guard panels (not included) or install them into an existing system to create a complete barrier around machinery. They have aluminum side frames that mount directly to the floor to keep them anchored in place. You can easily access parts for maintenance by removing the cover on the side panels.

In the event of a power outage, open them manually using a hand crank. These doors are only for use indoors.

Instead of pulling a chain or handle to open your steel roll-up garage door, push a button. These openers come with everything you need to convert your manual door into an automatic one. Simply slide them over your garage door’s drum axle. For smooth operation, they start and stop slowly to prevent the door from lurching and slamming to the ground. Similar to an automatic garage door, they’ll stop and reverse the door if the light beam sensing switch detects an obstruction in its path. Turn on the safety mode to lock the garage door and limit control to a single master remote. If there's a power failure, disengage these openers to manually open the door.

These openers fit most steel roll-up garage doors, also known as rolling sheet doors, with 9 _1/2" or 12" door drums. You can mount them on either side of the door. Do not use these openers with sectional or fabric garage doors.

Also known as jackshafts, these openers will stop and reverse the garage door's downward motion if it encounters an obstruction or the light beam between the opener's sensing switches is interrupted. During a power failure, use the manual chain hoist to move the door. These openers meet UL 325 safety standards for door operators and systems.

Conveniently carry your transmitter with your keys to remotely operate automatic overhead door openers. These transmitters are for Liftmaster openers that have Security+ 2.0 rolling code technology, which sends a new code with each use. They can operate three door openers.

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation. The lock is not included; use a 1 _1/4" long mortise lock with a standard cam.

Replace existing transmitters or team a transmitter and a receiver (not included) to remotely operate your automatic overhead door openers.

If you don't have your remote, you can still open and close automatic overhead doors with a private 4-digit PIN. Use these transmitters to operate one transmitter or receiver. The keypad is backlit for visibility in the dark.
