Strapping kits include a selection of items that work together to hold, store, transport, tension, and seal metal and plastic strapping. A strap is wrapped around a box, bundle, or item and the strap is then tightened and secured using a buckle or seal. Each kit is designed for use with a specific strap material. Kits can include wheeled strapping carts to store and transport coils around a facility, strap tensioners and sealers used to secure straps with strapping seals, strapping cutters, and strapping seals and buckles.
