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.

"B" base and 4 Traveling Slider
Locks

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.
