Adjustable Height Options

Particularly useful are the CL2(/M) and CL3(/M) clamps, which use one cap screw for height adjustment and another for lockdown, as shown below. This design allows a downward force to be directed onto any object, securely clamping the object and preventing slippage.

Options

  • CL5: General-Purpose Clamp
  • CL2: Heavy-Duty Clamp with Adjustable Height
  • CL3: Compact Clamp with Adjustable Height
  • CL6: Wedged for Use with RLA Series Optical Rails
  • CL4: Compact Clamp for Tight Spaces
  • CL8: Table Clamp for Ø1" and Ø1.5" Pedestal Posts

The CL Series Table Clamps are widely used when constructing optomechanical assemblies. Their ability to adapt complex, unforgiving layouts to any mounting hole pattern saves time and headaches, significantly reducing setup times. These clamps are used with 1/4"-20 (M6) cap screws and washers, which are available as part of our Screw Kits.

The CL5 table clamp is by far our most popular table clamp. Its simple design is compatible with most common optomechanics. It only requires one cap screw and washer to secure and the rounded edge increases the surface area where the optomechanic is contacted.

The CL2(/M) heavy-duty table clamp uses two cap screws: one in the 1/4"-20 (M6) tapped hole to adapt the clamp to virtually any height and another in the slotted hole to secure the clamp to the table. The extra-long design increases the torque exerted on the optomechanic being held.

The CL6 clamp features a wedged tip that is specifically designed to fit our RLA series of optical rails, allowing an RLA rail to be secured along any direction on a breadboard or optical table.
