Folding Heads

Schallert Enterprises’ Folding Head Linestop machines are a cost effective solution for stopping any line from 5” – 84” in diameter. The folding head linestop machines are inserted into the line through a reduced branch fitting, saving you on costs across the board. Smaller taps, smaller valves and smaller fittings are used to get the job done.

Jackscrews / Actuators

Our jackscrews, commonly referred to as actuators, drive the line stop machines into place. All jackscrews have the stroke length etched onto the chrome bar and can be viewed through a porthole near the base of the housing. We offer four different standard jackscrews, but we can customize any of them to fit your exact needs.
