Lancaster Pump Stretcher Replacement Jaws

Replacement Stretcher Jaws ONLY.   They are intended for installation in the Stretcher Cartridge. These are the original and only units made in the USA by Lancaster Pump.   Lancaster Pump holds the original patent for this metal Shrinker Stretcher concept. The Lancaster Pump Stretcher Shrinkers have been copied in China and their poor  imitations  are not near the quality of ones made in the USA. The Lancaster Jaws are a darker color indicating they are  heat treated.  The  heat treatment  process used on Lancaster jaws keeps the jaws  sharper  longer  than imports. Without sharp jaws the metal will slip in the jaws.   All the Lancaster Pump Jaws will have  "CB"  stamped on them. The Lancaster Pump pressure blocks won't break like imports.  The Lancaster cartridge cover will  not  bend and deform with use like the import cartridge body.  Please check out the broken and deformed ... IMPORT ... parts pictured. Lancaster Pump Stretcher / Shrinker tools will not let you down in the middle
