From Our Work
Gate Automation in Action
Why Commercial Property Managers Choose CSL24UL
Professional grade capacity, safety compliance, and smart monitoring built for high traffic properties.
Continuous Heavy Duty Operation
Supports gates up to 50 ft long and 1,500 lbs, rated for Class I, II, III, and IV vehicular gate applications, from multi family housing to restricted access government facilities.
24VDC Battery Backup System
Dual 12V, 7Ah batteries maintain standby power during storms, grid failures, and utility interruptions, keeping your gate operational when your property is most vulnerable. Solar ready for suitable applications.
myQ Smart Technology Integration
Centralized management allows for real time monitoring and control of multiple access points, generating usage logs and status alerts from any smartphone.
UL 325 Safety Compliance
Requires monitored safety inputs including photo eyes and edge sensors for every entrapment zone, with two independent monitored safety devices per zone.
Weather Resistant Construction
Robust housing, sealed accessory connections, and a commercial gear driven transmission reduce exposure to environmental elements compared to exposed chain or belt systems.
Security+ 2.0 Rolling Code Technology
Every signal between remote and receiver uses advanced encryption that changes with each activation, preventing code grabbing found on many standard gate openers.
What Makes CSL24UL Superior to Standard Gate Motors
Most standard gate motors are built for lighter residential gates under 1,000 lbs and fewer than 30 ft in length. The CSL24UL is built differently.
Most standard gate motors typically lack robust safety compliance, smart connectivity, and the mechanical durability needed for commercial operation. The CSL24UL slide gate is engineered from the ground up for continuous, high volume commercial use.
Commercial Gear Drive System
A commercial gear driven transmission provides superior holding power compared to chain drive alternatives. When the backdrive switch is set to Secure, the gate cannot be easily pushed open during power loss.
Soft Start and Stop Operation
Smooth start and stop technology reduces mechanical stress, extending operator life and minimizing noise, with controlled acceleration and deceleration for better long term reliability.
Wireless Dual Gate Communication
Wireless dual gate communication allows for easy installation without trenching, enabling coordinated operation of complex entry systems.
The CSL24UL also supports up to 50 Security+ 2.0 remotes, wireless keypad accessories like the KPW250, and loop detectors for vehicle detection, with unlimited remote control expansion possible through compatible access setups.
How It Works
How CSL24UL Installation and Operation Works
From site assessment to ongoing monitoring, every CSL24UL install follows a proven professional process.
1
Professional Assessment and Setup
Technicians evaluate gate dimensions, weight, track condition, power availability, and environmental exposure. The operator must be installed on a properly sized concrete pad, positioned correctly relative to the gate’s roller assembly.
2
Smart System Integration
The CSL24UL connects to existing safety devices, loop detectors, keypads, and the myQ platform. The control board includes adjustable open and close limits, reversal force sensitivity, and timer to close functionality.
3
UL 325 Safety Compliance
Installation must comply with UL 325 standards, including the addition of monitored entrapment protection devices. This coverage is verified during installation and again during monthly safety testing.
4
Ongoing Performance Monitoring
The myQ app provides real time gate status updates and maintenance alerts, letting property managers verify gate position, monitor access events, and receive notifications when service is needed.

Ideal For
Ideal Applications for CSL24UL in High Traffic Areas
If your gate falls within its rated conditions, the CSL24UL is purpose built for your application.
Industrial Facilities
Manufacturing plants, warehouses, and distribution centers requiring 24/7 access control benefit from the CSL24UL’s high holding power and reliable continuous duty operation.
Commercial Properties
Office complexes, shopping centers, and business parks with high traffic volume need a slide gate operator that will not degrade under constant use.
Storage Facilities
Self storage operations need reliable automated access throughout the day. The CSL24UL’s durability, combined with myQ remote monitoring, lets managers oversee gate operation without being on site.
Multi Family Housing
Apartment complexes and gated communities with frequent resident access generate high cycle counts daily. Anti tailgate features and quick close capability help prevent unauthorized entry.
Government and Municipal Buildings
Facilities requiring enhanced security and backup power find the CSL24UL’s Class IV rating, battery backup, and centralized access control integration essential.
The CSL24UL requires monitored external entrapment protection devices; this is not optional for commercial applications. Contact BD Garage Door & Supply to review fitment or configuration before setup.

Frequently Asked Questions About the CSL24UL
Quick answers to the questions we hear most about the CSL24UL and its installation.
The CSL24UL supports gates up to 50 ft long and up to 1,500 lbs. Your gate must be a slide type configuration with a rigid, straight structure and appropriate rollers and track. BD Garage Door & Supply provides a professional assessment at your location to verify compatibility, measure gate weight and dimensions, and determine whether any modifications are needed before installation.
The included dual 12V, 7Ah batteries provide standby power during AC power failures. The CSL24UL can perform up to 1,179 cycles on battery backup, though actual duration depends on gate weight, travel distance, and cycle frequency. For extended outages, the CSL24UL is solar ready.
Yes. Installation should be performed by an authorized technician. UL 325 compliance requires proper installation of monitored entrapment protection devices, correct wiring, limit and force adjustments, and safety testing. Improper installation can void the warranty and create serious liability.
Routine maintenance includes monthly testing of all safety devices, inspection of the chain and gear mechanism, sensor cleaning, battery health checks, and firmware updates via the control board. BD Garage Door & Supply offers scheduled maintenance service to keep your system compliant and operating at peak performance.
Yes. The CSL24UL integrates with modern access control systems through the myQ platform (myQ Facility and myQ Community), Security+ 2.0 accessories, loop detectors, wireless keypads, and expansion board options.
The operator carries a 5 year commercial warranty covering the motor and electronics. If the motor fails, the manual disconnect feature allows the gate to be operated manually using the included keys, or the backdrive switch can be set to Secure to keep the gate locked until service arrives.
