Ø1/2" Construction Accessories
Thorlabs' Angle Clamps securely fasten our Ø1/2” posts at precise angles (45°, 90° or 180°) to one another. In addition to the fixed angle options, we also offer a variant for 360° continuous adjustment (SWC). The holes of these clamps are double bored to provide two lines of stable contact. The RA180(/M) has one double-bored hole and a 1/4"-20 (M6) thread on the bottom, which allows this clamp to be directly threaded onto a post. The aluminum thumbscrews located at either side of the clamps secure the Ø1/2” posts in place once the desired position is achieved.
The RA90RS clamp allows a Ø1/2" TR post to be mounted perpendicularly to a Ø1.0" RS post. The design, which is based off of the RA90 Right-Angle Post Clamp featured above, combines a highly stable clamp flexure lock with a thumbscrew locking mechanism to provide a solution that enables a Ø1/2" post to be mounted perpendicular to a Ø1" post. The center-to-center distance between the Ø1.0" and Ø1/2" posts is 1" for the imperial version (25.0 mm for the metric version).

Thorlabs’ Mounting Joists provide valuable space-saving mounting options, ideal for crowded optical tables or breadboards. These mounts are compatible with our Ø1/2” and Ø1” posts and allow multiple optics may be mounted close together on a single joist, eliminating the need for multiple posts and post holders.
The PJ301(/M) enables centered-mounting (optics may be placed on both sides of post center) and features a centered, counterbored hole for an 8-32 (M4) cap screw for post mounting and counterbored slots for an 8-32 (M4) cap screw and #8 nut (M4 nut). This joist allows an optic to be offset by 0.40" - 1.40" (10.16 - 35.56 mm) from post center.
The PJ302(/M) enables offset-mounting (optics may be offset to one side only) and features counterbored slots for an 8-32 (M4) cap screw for post mounting and a counterbored slot for an 8-32 (M4) cap screw and #8 nut (M4 nut). This joist allows an optic to be offset by 0.40" - 2.70" (10.16 - 68.58 mm) from post center.
Please Note: Imperial nuts only fit the imperial joists; metric nuts only fit the metric joists (nuts included).
