RoHS COMPLIANCE

Please note that Wakefield part numbers designated with an “E” in this catalog denote new parts in compliance with the RoHS ini-

tiative, with the exception of our Precision Clamps. Wakefield will still continue to offer non-RoHS compliant versions of these parts.

Please be aware that many Wakefield Standard parts have always been compliant since their design inception and therefore will not

carry the “E” designation.

Wakefield requests that you refer to the RoHS compliance tool on our website at www.wakefield.com to verify RoHS compliance. If

you require further clarification or information regarding RoHS, please contact the factory.
