Linear Operator Standard Features


Efficient design results in ongoing energy savings. Ultra-low standby power mode reduces electricity usage.

Ultra-Smooth and Quiet Operation

Variable speed operation delivers ultra-smooth, quiet performance, increasing long-term reliability

Belt Drive or Chain Drive

Choose from our exceptionally quiet belt drive or our solid-performing chain drive.

Safety First, Safety Always

If the obstacle-sensing beam is crossed when the door is closing, the door reverses to fully open.

Park or Reverse Door

To permit both ventilation and access, the garage door can be stopped and parked during either upward or downward travel.

Secure, Responsive Remote Control

Linear remote controls operate over a long range and employ high-security technology.

Deluxe Wall Station

All controls are large, clearly marked and illuminated (door UP/DOWN control, courtesy light switch, and vacation mode).

Automatic Courtesy Light

A built-in 100W MAX light illuminates the garage for five minutes every time the operator is used.

Easy Door Release

When you need to open or close the garage door manually, simply release the operator’s quick-disconnect trolley.

Assurance Through Self Checks

The operator’s self-diagnostic system continually checks to see whether everything is working properly. In the unlikely event of a problem, it will pinpoint the trouble and let you know by flashing the courtesy light. You can often solve the problem on the spot with a call to your Linear dealer.
