Ratchet Lock 

The ratchet lock can be activated or deactivated, depending upon the application.

Operation with Ratchet 

The ratchet on the EXPCRL is spring loaded. It is designed to function in all acceptable 

mounting configurations.

Operation without Ratchet 

Deactivate the ratchet by pivoting the lock-out bar to the lower position. This will remove the ratchet 
pawl from the path of the ratchet plate. Locate the dimple on the lock out bar in the hole provided.

WARNING:

 Do not activate the ratchet abruptly. Sudden activation may cause excessive shock loads to the ratchet pawl which may 

cause lock-up and/or breakage.

  

Cable Installation 

Cable is factory installed and sealed. Consult factory for changes. 

Spring Tension Adjustment 

WARNING:

 Do not allow cable to retract without restraining the retraction speed. Walk the cable back to the reel during the spring 

tension adjusting process. Always maintain two full cable wraps on drum at maximum cable extension, size cable accordingly. 

1. The EXPCRL reels come with pre-tension from the factory. Some adjustments may be required to meet specific application 

requirements.

2. To assure that the cable will retract properly and operate under the correct tension for intended application; the reel should be 

tested. Securely mount reel before testing with cable installed on drum and end of spool cable not connected, proceed with the 
next steps.

3. Pull the cable out to the intended travel distance and allow it to rewind. This procedure should be repeated five (5) to ten (10) 

times in order to set the spring. Walk the cable back to the reel during the spring tension adjusting process.

Rotate Spool while holding Cable to Test the Spring Tension 

4.  With all the cable wound on the reel, grasp the end of the cable and rotate the drum and cable together in the direction of pay 

out in order to pre-tension the spring. The number of pre-tension turns is determined by cable size and footage. Usually, four to 

sixteen turns is sufficient, but additional turns may be used if testing indicates that the cable will not fully retract as desired with 

just four turns.
