T-H Marine CBR4 Cable Boot Retaining Ring – 4.5", Black Vinyl, UV & Fuel Resistant
The T-H Marine CBR4 is a 4.5" black vinyl cable boot retaining ring for securing and finishing cable boot installations in larger splashwell or bulkhead openings. The retaining ring locks the cable boot in place in the opening so it doesn’t pull through under cable tension, and provides a clean finished appearance at the installation panel. Constructed from rugged black vinyl that resists UV rays, gasoline, and oil.
For the smaller 3" retaining ring, see the T-H Marine CBR1 Cable Boot Retaining Ring (3"). For splashwell cable boots, see the T-H Marine CB1 (3") or CB2 (2").

Parts Desk Insights
Best Use Case: The CBR4 is the correct retaining ring when your cable boot installation uses a 4.5" opening — the larger of the two T-H Marine cable boot ring sizes. Like the CBR1, it serves two purposes: locking the boot in place so it doesn’t pull through under cable tension, and providing a finished appearance at the panel. The 4.5" size is suited for larger splashwell or bulkhead openings where the 3" CBR1 would be too small. Confirm your cable boot and opening size before ordering — the CBR4 and CBR1 are not interchangeable.
