LiftMaster OES-SD24 24 Foot Sectional Door Optical Edge Kit
The LiftMaster OES-SD24 is a 24 foot optical edge system kit for compatible commercial sectional overhead doors. It provides a monitored rubber edge assembly for doors that require a longer sectional door safety edge.
What This Part Does
This kit is used when a commercial sectional door needs a 24 foot edge length or when the edge must be cut to suit a wider door. The infrared optical sensor design helps provide monitored protection without a traditional contact strip.
Compatible With
This LiftMaster OES component is commonly used with select LiftMaster commercial door operator installations that require monitored entrapment protection. Compatibility depends on door type, edge profile, operator safety input, and the installed OES system components.
- Select LiftMaster Logic 5.0 commercial door operators
- Select LiftMaster MAXUM commercial sectional door operators
- Select LiftMaster medium-duty trolley and jackshaft commercial operators
- Select standard-duty and heavy-duty LiftMaster commercial door operators
- Commercial sectional overhead doors requiring a 24 foot edge kit
- Applications that require a monitored optical edge device
Important Compatibility Notes
- Use sectional door OES parts only on compatible sectional door applications.
- Use rolling door OES parts only on compatible rolling door applications.
- Do not mix edge profiles, sensor kits, mounting kits, or wiring components unless the LiftMaster OES instructions support the combination.
- The commercial operator must support the required monitored edge input for the installation.
- All safety devices should be tested after installation before the door is returned to service.

Technician Note
Match the OES component to the door type and the original installation, not just the LiftMaster brand name. Sectional door edges, rolling door edges, sensor kits, coil cords, junction boxes, and mounting kits work together as a monitored safety system. A similar-looking component may not be correct if the edge profile, door style, wiring, or operator input is different.
Before Ordering, Confirm
- Original LiftMaster OES part number or kit number
- Door type: sectional overhead door or rolling door/grille
- Required edge length or field-cut edge material
- Existing optical sensor, junction box, coil cord, and mounting hardware condition
- Commercial operator model and monitored edge input requirements
- Whether the job requires one replacement component or a complete OES kit
Professional Advisory
Optical edge systems are safety-related components on commercial doors. Installation, wiring, adjustment, and testing should be performed by a qualified commercial door technician. Do not bypass a monitored safety edge or operate a commercial door with missing, damaged, or untested entrapment protection.
Important Ordering Warnings
- Do not assume sectional and rolling door OES parts interchange.
- Do not use rubber edge material alone when the installation requires sensors, wiring, and monitoring components.
- If the operator displays a monitored edge fault, inspect wiring, sensor alignment, coil cord, and junction box before replacing parts.
- Confirm package contents because some OES listings are complete kits while others are individual replacement components.
Questions & Answers
When should I use OES-SD24 instead of OES-SD16?
Use OES-SD24 when the sectional door requires a longer edge length than the 16 foot kit provides or when the installation calls for a 24 foot field-cut edge assembly.
Is the rubber edge cut to length in the field?
Yes. The premium rubber edge is commonly cut to the required length at the installation site, provided the installer follows the edge system instructions.
Does this kit work with every LiftMaster commercial operator?
No. The operator must support the required monitored edge input and the installation must follow the operator and OES system instructions.
Is OES-SD24 for sectional doors or rolling doors?
OES-SD24 is for sectional door optical edge applications. Rolling door installations use a different edge profile and mounting approach.
Why is the monitored edge important?
A monitored edge allows the compatible operator to confirm that the entrapment protection device is connected and functioning before normal operation.
