Single Compression vs Double Compression Cable Gland
Which Type is Right for Your Cable Termination?
Cable glands are used to terminate cables at panels, junction boxes, and equipment entries — providing a secure mechanical grip and environmental seal. The two most common types are single compression and double compression glands. Choosing the wrong type can compromise your IP rating, cable retention, and safety. Here is a complete guide from JSR Group.
