Watson

Adjustable Location (AL) Series

FEATURES
These threaded body cylinders install quickly and easily without requiring special mounting devices. Just drill the proper hole size, “pop” in your cylinder, and adjust it to position with the pair of jam nuts furnished on most models. Or tap a hole and lock into exact position with a single jam nut.
The AL-Series cylinders are electroless nickel-plated for excellent corrosion resistance and a gleaming appearance.
