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.

The AB90H and XE25A90 Right-Angle Brackets can be used to fasten 25 mm rails to each other using a T-Nut (sold separately) or to an optical table. Both intended for use with 1/4"-20 (M6) cap screws and washers, the AB90H has a total of two 1/4" wide slots of lengths of 1" (25.4 mm) and 0.5" (12.7 mm), allowing for additional flexibility in positioning the rails on a breadboard, while the XE25A90 has two counterbored holes.

These brackets are ideal for fastening our optical enclosures to an optical table or breadboard.
