  • Mount 25 mm Rails Horizontally on an Optical Table or Breadboard
  • 1" (25.4 mm) Long Clearance Slot for 1/4"-20 or M6 Screws
  • Insert Anywhere Along Rail

The XE25CL2 Table Clamp mounts a 25 mm rail horizontally to a 1/4"-20 or M6 tapped surface by using a rail channel. It holds the rail in place using a side-located rail channel, while leaving the top rail channel free to accept enclosure panels or T-Nuts. The clamp features a 1" (25.4 mm) long clearance slot compatible with 1/4"-20 and M6 screws, providing mounting for imperial and metric tables.
