Features

  • Provides Stable and Rigid Mounting of 34 mm Rails and Components
  • Easy to Adjust and Position by Sliding
  • Clamp Design Permits Rails to be Dropped In and Tightened Into Place
  • Low-Profile Brackets Rotate by Fixed Angles in Three Dimensions

Thorlabs' clamps and brackets for 34 mm rails are fundamental building blocks of two- and three-dimensional rail constructions.

Clamps
Our clamps securely fasten two rails together and feature fixed and variable rotation options. They are designed with a wide opening that tightens shut around the dovetailed rail, allowing the rail to be added and removed without having to disturb existing components. The clamps can be slid into position and locked in place.

Brackets
Our rigid angle brackets provide rotation by fixed amounts and enable three-dimensional constructions. They are designed to be used in combination with the clamps.

Thorlabs offers a wide and growing complement of accessories for 34 mm rails, including clamps and angle brackets, breadboard mounts, rail carriers, mounting platforms, lens tube adapters, and rail joiners. Together with size adapters that incorporate 66 mm and 95 mm rails into an XT34 setup, these tools provide a complete family of rigid, versatile building blocks suited for virtually any optomechanical setup.

XT34C2 Double Dovetail Clamp Holding an XT34D2-30 Mounting Platform and RSP1 Rotation Mount
  • Clamp Between Rails or Accessories
  • Orient Rails Parallel to Each Other
  • XT34C1: 15 mm Long Clamp
  • XT34C2: 30 mm Long Clamp

Our Double Dovetail Clamps for 34 mm Rails securely join XT34 rails and components in a parallel orientation. They are available in two lengths: 15 mm and 30 mm.

Using two XT34C1 clamps as a pair prevents torsional strains and keeps two rails parallel over the entire length spanned by the clamps. If a single-clamp solution is preferred, then we recommend the XT34C2, which provides additional surface contact. It is also perfectly sized to attach components on an XT34D2-30 mounting platform, as shown to the right.
