Locking Clamp Positioned Under Our PSY321 Breadboard Mounting Bracket, Holding it in Place and Allowing for Free Rotation of the Bracket

• Retain the Position of Ø1.5" Post Mounted Accessories
• Hinged Clamp Design Allows for Installation Without Removing Existing Shelves

Thorlabs PSY322 Hinged Locking Clamps are the ideal solution for preventing the unwanted movement of accessories along the axis of the post. Locking the clamp in place (5 mm hex key included) directly under a post-mounted accessory, as shown to the right, prevents the accessory from sliding down the post when it is loosened for adjustments. This also allows mounted shelving or brackets to be freely rotated around the axis of the post to a needed position at any time.
