Thorlabs' angle adapters for 95 mm rails are fundamental building blocks of two- and three-dimensional rail constructions.
Five-Way Corner Cube
The XT95C1 Five-Way Corner Cube tightens into the M6-tapped holes in the ends of a standard 95 mm rail and orients up to five standard rails at right angles. Each face of the cube contains a large clear aperture that allows the entire rail interior to be used as a beam path.
In order to install rails on adjacent faces of the corner cube, we recommend using our SH6M10LP Low-Profile Channel Screws. The reduced cap height of these screws prevents neighboring screws from interfering with each other.
Rail Carriage
The XT95P11(/M) Drop-On Rail Carriage fastens to the end of a standard 95 mm rail using four M6 cap screws and features a swinging clamping arm designed to hold a second 95 mm rail at a right angle. The side-mounted locking screws can be accessed with minimal effort.
Pivot Support
Our XT95P4 Pivot Support is a heavy-duty joint that connects two rails while providing up to ±90° of variable rotation. Once the rails are at their desired angle, they are fixed in place using a hex wrench.
Thorlabs' product family for 95 mm rails includes angle adapters, leveling feet, a base plate, and a vacuum adapter that supports pressures down to 10-6 torr. In addition, we manufacture mounting platforms and T-Nuts that provide compatibility with standard optomechanics. Together with size adapters that incorporate 66 mm rails into an XT95 setup, these tools provide a complete family of rigid, versatile building blocks suited for virtually any optomechanical setup.

The XT95C1 Five-Way Corner Cube secures rails end to end or at right angles. The five mounting faces of the cube contain a centered, Ø2.83" (Ø71.9 mm) clear aperture that leaves the entire rail interior unobstructed. Each face also has four through holes that are positioned to align with the inner M6-tapped holes on the end of a standard 95 mm rail. The cube is machined from a single block of aluminum to ensure the perpendicularity and parallelism of the five mounting surfaces.
Please note that the caps of standard M6 cap screws will interfere with each other when installed in neighboring faces of the cube, preventing the rails from being fastened down. We therefore recommend the use of our SH6M10LP Low-Profile Channel Screws, sold below, which feature a shortened cap height.

The XT95P11(/M) Drop-On Rail Carriage contains four counterbored holes, positioned such that the carriage can fasten to the inner M6 taps on the end of a standard 95 mm rail. In this orientation, the swinging clamping arm, which tightens using two side-mounted 1/4"-20 (M6) locking screws, is free to secure another 95 mm rail at a right angle. The arm provides ample clearance to lift the rail off when the locking screws are loosened.
Alternatively, this rail carriage can be fastened directly to a rail side to provide a mounting surface for optomechanics. The XT95P11(/M) contains a 3" x 3" (75 mm x 75 mm) array of 1/4"-20 (M6) taps and counterbores, along with a centered 1/4" (M6) counterbore.

The XT95P4 Pivot Support is a heavy-duty joint that offers ±90° of variable rotation. It is ideally used to construct large-scale, non-rectangular structures. Once the attached rails have been set to the desired angle, tightening the side-mounted 3/4" bolt and nut combination locks the joint in place.
Each side of the joint contains four through holes at the corners, positioned to fasten the joint to the XT95P3 Base Plate or the outer M6 taps on the end of a standard 95 mm rail. The XT95P4 also features four M6 taps on each side that enable mechanical compatibility with the XT95P11(/M) Rail Carriage sold above. The combination of the pivot support and rail carriage, shown to the right, allows two 95 mm rails to be mounted at an arbitrary angle starting anywhere along the base rail.

Our SH6M10LP Low-Profile Screws feature a shorter cap height than standard M6 cap screws. They are required to fasten an XT95C1 Five-Way Corner Cube to a 95 mm rail when two rails are being mounted at a right angle because their reduced cap height prevents neighboring screws from interfering with each other.
