Buckles & Seals

There are choices available for creating a seal or join with polypropylene hand strap. Plastic and wire buckles are generally used in low volume, light to medium weight strapping applications. Use wire buckles in place of plastic buckles where extra strength is required. Seals are used for strapping applications that require a more secure hold.

  • Plastic Bucket

    The strap is threaded onto the plastic
    buckle and then pulled tight by hand or
    with a tensioner. When the tool is
    released the strap will stay tight.

  • Wire Buckle

    The strap is threaded onto the wire
    buckle then pulled tight using a
    tensioner. When the tool is released
    the strap will stay tight.

  • Metal Seal

    The strap is tensioned using a tensioner, then a metal seal is used with a sealer to compress the seal tight onto the strap. Serrated seals are designed with threads, or serrations, on the inside of the seal to grip polyester or polypropylene strapping and prevent it from slipping.
