STEEL PNEUMATIC UP NOTCH SEALER, .024” (.61mm) to .035” ( .90mm)


Our JEM-STPDN Series tools are highly recommended Double Up Notch Sealers.  With a single press of the trigger, this tool creates 4 notches compared to the 2 that a single up notch sealer creates.  Why is this important?  The 4 notches create a much stronger joint efficiency compared to a single up notch sealer.  Most applications require 4 notches to be created, therefore, getting a tool that creates all 4 notches at once creates a more seamless workflow and is easier on the tool operator.  Not to mention, this creates a safer operation for the employer as it prevents the employees from forgetting to apply a second set of notches to the strapping.
