Build a custom clamping system for holding lightweight objects such as beakers and laboratory equipment. First choose a base, and then add rods, connectors, and clamps.
Stainless steel components provide excellent corrosion resistance.
Rod-to-rod connector holds two rods at a 90° angle.
Clamps require a connector to attach to rods.

Spring Clamp Workholders
Secure small parts in spring clamps to keep hands free for soldering, gluing, and assembly. The workholder’s arms are mounted to a base and adjust for positioning work at almost any angle.
Workholders that cannot be sold to Canada are restricted by local energy efficiency requirements.

Screw Clamps
Use mounting bases to attach screw clamps to flat surfaces. Their threaded portion is machined at a slightly downward angle so the clamp can get a strong grip on the workpiece. Length is measured from under the screw collar.

![](/prerenderstable/mvPRE/contents/gfx/imagecache/554/5545n11-f6@halfx_82p0a_1717535380.png?ver=imagenotfound)
Stabilize and precisely position your indicator with these weighted bases. Attached to the base, these holders have a jointed arm for moving your indicator up and down and in and out. Tighten the knob on the arm to lock it in place and use the fine-adjustment clamp for angling your indicator just right. Made of granite, the base has an extremely tight flatness tolerance, so it creates an accurate reference point for inspection work. It also means you can easily slide your workpiece in and out.
