MA7637 Mustang Belt Extender for 1.5IN Buckle
The belt extender allows wearers with larger size requirements to use most Mustang Survival inflatable PFDs and will add 12" to the waist belt. This belt extender fits PFDs with 1.5" buckles.
In the United States, wearing the belt extender voids the US Coast Guard approval UNLESS the wearer has a chest size over 130cm or 52inches, in which case wearing an adult universally-sized PFD with a clip-on body strap extension DOES NOT void the approval.

This extender belt does not fit inflatable PFD models with 2" webbing - this includes older models of MD3052, MD3054, MD3082 and MD3084 and any model with the lot number beginning with a W.
