Lead screw lock TL

Slider Lock SL

Traveling Slider Lock TSL

Locks for linear UniSlides are available in three types

Thumbscrew-on-Lead Screw Lock This is the most common lock. It uses a simple thumb screw to secure the lead screw in the end bearing block which is longer than the standard end bearing block. See table below. This lock type is not useful for Rapid Advance Style UniSlides because the slider can still move. I want to use this lock with a Scale and Vernier Model.

Slider Lock This is a thumbscrew located at the midpoint of the base length. The screw tightens against a 90° step milled into the side of the slider, parallel to the side, preventing movement of the slider. This lock works if slider length, S, is equal to or greater than ½ the base length L. If not, you need multiple locks spaced along the base. To order lock on the right side, append “-SLR” to the model number. For a lock on the left side, add “-SLL”. See drawing below to identify right and left sides. What is the cost?

Traveling Slider Lock This locking plate attaches to the slider; the thumb screw presses against the outside edge of the base. It can be mounted on either side of the base. The lock is available in all Series but limited to Free Sliding, Screw Motion, Graduated Knob Types. Slider height is increased by 3/16" Series A15, 1/4" Series A25 and 3/8" Series A40, A60 and B90.

On models with a scale and vernier, the vernier is offset to the right to avoid being obscured by the payload. When adding a thumb lock to these models, we cut away the vernier plate (shown in pink) to avoid hitting the thumbscrew lock.
