The R&B Cyli-Strap Model CYL-1 is a 1.5-inch nylon webbing transport strap that enables firefighters and rescue operators to carry two spare SCBA cylinders hands-free during high-rise, RIT, confined space, and HazMat operations.

The Cyli-Strap converts two loose, cumbersome cylinders into a single manageable sling load using a girth hitch attachment system at each sewn end loop. With a 2,500 lb tensile strength and a fixed 42.5-inch length, the strap positions cylinders at hip level to prevent stride interference and minimize ground clearance issues during stairwell ascent. The high-visibility red color supports rapid identification in low-light and smoke-filled environments.

Attachment requires no knot-tying. Passing the webbing body back through the sewn end loop forms a girth hitch around the structural neck of the cylinder, below the valve assembly. The system is self-tightening by design: cylinder weight provides the tension that cinches the hitch securely, and releasing that weight during doffing immediately creates slack for removal. This mechanical simplicity supports reliable deployment under operational stress, even with gloved hands.

The strap is rated for equipment transport only and must not be used for rappelling, hoisting personnel, patient rescue, or safety lanyard applications. Operational capacity is two standard SCBA cylinders. Pre-deployment inspection of the full webbing length and both sewn end loops is a required step before every use, with immediate retirement from service if cuts, melted fibers, damaged stitching, or prior shock loading are identified.
