Swing Clamps and Arms
Low Profile Clamp Time and Flow Rates, Low Profile Clocking
TuffCam™ Clocking Features Three clocking features have been added to Vektek’s Low Profile Swing Clamp line. Customers have requested the clocking features to help improve and speed-up arm changes. A drill point on each clamp standardizes arm location at a particular position. An additional two orientation drill points reside 120° out from that position and each other. Access to the positioning feature is through the back or side of the arm, making modification a snap for users. Each arm position can have its own specification.

NOTE: Arm Length and Pressure Limitation Graphs in end of section. The above flows are maximum recommendations and clamp times are minimum recommendations. - For upreach and double arms, use extended arm flows and times. - When using custom arms the extended arm flows and times are to be considered the limiting factor. - The actual time to position the clamp will vary by custom arm configuration and may require customer testing in specific application to establish limits.
