With a small amount of drug-store rubbing alcohol, the bands can be installed on Trumark slingshots, or any other brand slingshot with round prongs, quickly without the use of tools, strings, or glue. The best way to extend the life of the powerbands, is to condition them against destructive elements with 303 Aerospace Protectant.

Both left and right bands are cut from one length of tubing so they are "matched" (balanced) for accurate shooting. CAUTION: Powerbands that are folded and packaged curled will take on a "set", and will not shoot accurately when installed. Trumark pure, surgical-latex powerbands are all packaged STRAIGHT in air tight, sealed blisters that guards against deterioration before installation. More on powerband life. If the package is left sealed, the bands will stay fresh, and can be stored for long periods of time. Instructions on how to install the bands are included on package. 225 Yard + Range!
