This paper towel holder mounts directly onto the side rails of Milwaukee Packout modular tool storage systems. The snap-on attachment locks into the rail channel with a firm grip that stays put whether your setup is stationary on a workbench or loaded on a cart. No drilling, hardware, or permanent modifications are required. The holder clips on and clips off for repositioning whenever your workspace layout changes. Installation takes seconds. Constructed from ABS thermoplastic, the holder is built to handle the conditions found in workshops, garages, and job sites. The material resists impact and maintains its shape through temperature changes and regular use. The holder accommodates standard and select-a-size paper towel rolls on a smooth spindle. One-handed tearing is possible without the roll spinning freely or detaching. Reloading is simple with the open-end design. Dimensions and rail channel spacing are matched to the Milwaukee Packout side rail profile for a flush, rattle-free connection.
