Mastlock
Tower Accessory

DXE-MASTLOCK

The DX Engineering Mastlock Tower Accessory is custom made for Rohn and Amerite Towers. Using this enables you to lock your tower
mast in position allowing you to remove your rotator without having the mast slip downward. Also great for locking the mast in position to
avoid the antenna turning when doing antenna maintenance. Using two DXE-MASTLOCK assemblies is suggested to keep the mast centrally
located. The DXE-MASTLOCK is made from 0.250” thick, 6061-T6 aluminum. Comes with proven quality DX Engineering saddle clamps
including stainless steel hardware for long lasting durable strength. As with all stainless steel hardware, a good quality Anti-Seeze such as Jet­Lube SS-30 (part number JTL-12555) must be used to avoid galling. When installing, tighten all bolts evenly.
