Features

These accessories enable vertical mounting of optical rails with 50 mm or 75 mm sides. The right-angle brackets can be used as rail corner mounts or for direct mounting to our breadboards and optical tables. Gusset plates are used to reinforce rail construction corners.

Thorlabs' accessories for assemblies made of 50 mm or 75 mm rails include T-nuts, low-profile channel screws, rail joiners, and a plastic channel insert for use as a dust cover, panel holder, or cable router.

The XE50A90 and XE75A90 Right-Angle Brackets can be used to fasten 50 mm and 75 mm rails, respectively, to each other or to an optical table. Each bracket can be secured to an optical rail by screwing it to T-nuts (not included) inserted into the rail channels. The XE50A90 and XE75A90 brackets have two slots on each leg with 0.99" (25.2 mm) or 1.98" (50.4 mm) spacing, respectively, for compatibility with either imperial or metric breadboards. Either the XE50A90 or the XE75A90 bracket may be used with our 50 mm x 75 mm rails, depending on which side of the rail(s) the bracket is attached to.

  • Connect Two Rails at a 90° Elbow
  • 1/8" (3.2 mm) Thick Anodized Aluminum
  • For Use with Low-Profile 1/4"-20 (M6 x 1.0) Channel Screws and T-Nuts (Sold Separately; See Table to the Right for Details)

These gusset plates are used to create strong 90° elbows using our 25 mm, 50 mm, and 75 mm rails. They provide reinforcement similar to the right-angle brackets sold above but do not block the inner channels of the elbow joint, instead leaving them open for hardboard or plexiglass panels. Each gusset plate features mounting holes designed for use with low-profile 1/4"-20 (M6 x 1.0) channel screws (10 mm max length) and matched T-nuts (both sold separately). When attaching rails of different sizes, we recommend mounting the smaller rail using multiple holes along the base of the gusset plate to provide additional rigidity, if possible.

To assemble, insert the screws into the gusset plate and loosely thread them into nuts on the back. Then slide the nuts into the rail channels and align the rail ends. With the rails aligned, tighten the channel screws.

  • 1/8" (3.2 mm) Thick Anodized Aluminum
  • For Use with Low-Profile 1/4"-20 (M6 x 1.0) Channel Screws and T-Nuts (Sold Separately; See Table to the Right for Details)

These gusset plates are used to create strong three-way junctions using our 25 mm, 50 mm, and 75 mm rails. They provide reinforcement similar to the elbow gusset plates sold above but with additional mounting holes to form a tee. Each gusset plate features mounting holes designed for use with low-profile 1/4"-20 (M6 x 1.0) channel screws (10 mm max length) and matched T-nuts (both sold separately).

To assemble, insert the screws into the gusset plate and loosely thread them into nuts on the back. Then slide the nuts into the rail channels and align the rail ends. With the rails aligned, tighten the channel screws.
