Clear Mechanical Push Button Lockout

The Master Lock S2153 is a transparent polycarbonate lockout device designed for industrial safety procedures. It isolates a single push-button or rotary switch to prevent accidental machine activation during maintenance. The hinged cover allows quick application and removal without tools. This unit suits authorised personnel managing lockout-tagout compliance on control panels.

Fits buttons from .89 to 1.2 inches diameter

The critical specification is the adjustable button-diameter range of .89 to 1.2 inches. The device clamps securely over push buttons or rotary switches within this window. It accepts one padlock with a shackle up to 5/16 inch diameter. If the target switch falls outside the stated range, the lockout cannot be installed safely.

Hinged removable cover frees the switch when work

Installation is tool-free: open the hinged cover, position the unit over the switch, close and secure with a padlock. The clear polycarbonate body lets operators verify switch position at a glance. When maintenance finishes, removing the padlock restores immediate machine access. The compact footprint of 1.89 by 2.3 by 2.73 inches fits crowded panels without blocking adjacent controls.
