Closed or Thread-on seals for steel strapping are threaded onto the strapping prior to tensioning. They are typically used for heavy duty steel strapping applications. 

 

Magazine Seals for steel strapping are interlocked into clips for easy loading into many combination tools and strapping machines.

 

Snap or Open seals for steel strapping are snapped onto straps before or after tensioning. When applied before tensioning, they maintain strap alignment. This eliminates the need to pre-thread which assists in speeding up the strapping process. 

 

Push or Overlap seals are used in conjunction with steel strapping for irregular shaped packages. The push seal withstands the stress of the tensioner pushing against the seal but do require pre-threading. 

 

Semi-Closed or Open Flange Seals for steel strapping are similar to snap on seals but are designed for heavy duty applications. The closed leg is hooked over the strap and the seal is then snapped down into position.
