Compare integral straps and separate harnesses
Identify what carries the attachment and what comes in the box.
Look at the pieces separately
An integral strap is part of the sleeve. A harness set may have a separate mount or ring. Compare the included parts and check whether any piece can be replaced.
Confirm the connection standard
A hollow attachment may have an outside base dimension and a different usable opening. If you already have a harness, ask which ring or attachment the manufacturer confirms will fit.
Separate an extension from a general sleeve
Some sleeves are open-ended and do not add a solid tip. The sleeve measurement guide explains how to read cavity, overall and added lengths.
