General information

Features and applications

Cam lever is a device which allows a quick and secure clamping.

The LAC-R model with adjustable ring-nut (ELESA patent) offers quick and secure clamping. The knurled ring-nut on the base allows to adjust the clamping force applied while locking the lever in the desired position.

Other executions

Special executions on request

Cam clamps with connection element, not drilled for a better cleaning (for sufficient quantities).

Instructions of use

Recommendations for assembly

LAC-B, LAC-SST, LAC-B-R and LAC-SST-R with threaded hole. The screw where the cam lever is mounted must protrude from the assembly surface by a maximum length of h1 max from the end-stop as shown in table and Fig.1. The user will notice the h1 max value is reached as the screw rests on the end-stop in the connecting element.

Instructions for clamping and adjustment

LAC: lift and rotate the lever clockwise until it stops, then, to complete clamping, lower the lever whose fulcrum is an eccentric cam which controls the base by rotating.

LAC-R: rotate the lever clockwise until it stops.

Fine adjustment: rotate clockwise or anti-clockwise the knurled adjustable ring-nut to calibrate the clamping force and put the lever in the desired position. The ring-nut is marked with minimum and maximum adjustment values: half a turn is enough for adjustment.

Clamping: lower the lever whose fulcrum is an eccentric cam which controls the adjusting base by rotating.
