B&O HP/SK-100

Beyer & Otto HP/SK-100


The B&O model HP-SK/100 is a manual sealant gun manufactured for the use of Semco and Techcon cartridges. Designed with a lightweight, retractable holder system, the HP-SK/100 does away with the standard steel tubed cartridge holders and can be used with or without the retainer.

This unique system (patent pending) only requires one cartridge holder to hold 2.5 oz, 5 oz, 6 oz, 8 oz and 12 oz cartridges. It is engineered for smooth dispensing, and the holder is designed to provide a full view of the cartridge, allowing the user to see the level of fluid inside the dispenser at all times.

This high end manual gun is a manually operated device with a trigger leverage of 8:1.
