Small Interlocked Safety Shield

The TR-1 small interlocked safety guard with a curved screen includes robust safety features.

  • Shield Size: 4 3/4″ x 7 3/4″ (120mm x 200mm)
  • Vertical adjustment: 4″
  • Impact-resistant polycarbonate (Lexan™) shield
  • Built-in tamper-resistant electrical safety interlock switch
  • The guard is adjustable vertically.
  • Mounted on a steel bracket that includes four mounting holes

The shield helps prevent entanglement hazards by protecting the rotating parts of a machine.  This guard protects against projections such as chips and coolant if used on a small drill press.  This guard will help prevent ejections from accidentally leaving chuck keys inside the drill chucks.  Customers can also buy self-ejecting chuck keys for added safety.  Click here to see our chuck key selection.

These shields meet or exceed OSHA, ANSI, and CSA standards for machine safety guarding.  You may also be interested in the big brother version of this guard: TR-6, Medium Interlocked Safety Shield (Click Here).
