Hand Strapping Tools for Steel Strap

Samuel A337


The A337 Manual Sealless Tool with MicroLock is suitable for standard, vertical, and horizontal applications across all industries. Its MicroLock sealless system guarantees maximum security against steel strapping joint unlocking.


The A337 features a special tensioning system which prevents minor tension loss, making it ideal for products requiring high tension and seal strength.  The advanced sealing technology and the individual tool adjustment for specific strap thickness on the A337 provides better join efficiency than tools using a separate seal.  If strap tension is lost during storage or shipment the joint will not unlock.
  • High seal joint efficiency of 80% with the patented sealless joint technology
  • Microlock joint prevents seals from unlocking, providing greater load security
  • Suitable for regular duty and high tensile steel strapping
  • Can handle steel strapping up to a thickness of 0.64mm / .025"
  • No loss of strap tension with the wheeling tensioning system
  • Sealing mechanism is completely closed, preventing damage from dust and debris
  • Cutting and sealing depths can be easily controlled with built in adjustment screws
  • Wearing parts such as the feed wheel, die and cutter are easy to replace with common tools
