Multi-purpose heavy-duty clamps feature an innovative closed yoke construction
that minimizes contamination and corrosion of internal components. The unique
design enables secure gripping and positioning with added strength and durability.
Available in both single and dual prong adjustment, prongs open gradually to maximize grip size without binding. Both designs feature precise pressure regulation when gripping glassware surfaces to reduce the chance of breakage.
Clamps are constructed with extension rods for easy attachment to lab-frames and other apparatus. Supplied with vinyl and fiberglass sleeve prong covers for high temperature applications.

Specialty
Swivel Clamps
Used to hold apparatus near the lab-frame. Unlike extension clamps, the swivel
clamps have an integral holder for attaching to a lab-frame or other apparatus. Built-in holder grips rods up to 19 mm (0.75”) in diameter and is adjustable for
forward or reverse-facing adjustment screws. Shaft wing-nut allows the holding
angle of the swivel clamp to adjust through 360° of rotation and can be locked in
place once desired position is achieved. Nickel-plated zinc construction. Supplied
with vinyl and fiberglass sleeve prong covers for high temperature applications.

simple lattice adjustment. Entire apparatus is supported on sturdy, counter-weighted
cast iron feet, which may be bolted to the floor for added stability required in top-heavy installations.
