Southco's New Series of Cam Latches Offers Adjustable Grip For Custom Fit

  • 3 min read
The E5 series provides flexibility in grip adjustment to overcome door tolerance inconsistency and permanent gasket setting. For applications with door gasketing which have a tendency to set permanently under a prolonged compressed state, the flexible grip adjustment provided by the E5 corrects this issue by allowing the grip to be readjusted to provide optimal door closing or gasket sealing. The ramp profile of the cam also acts as lead-in to assist door closing, and provides up to 1mm of compression. Tested to NEMA 4 and IP65 standards for water and dust protection, the E5 provides ingress protection and is suitable for use indoors and out.
With deep offset, standard offset, and straight (no offset) options, the latch covers a wide range of grip distances. The metal cam features a plastic cap that minimizes noise when making contact with the keeper, delivering robust, scratch-free engagement with frame and protecting decorated or coated finishes. Additionally, the E5 Cam Latch features the same panel hole prep as the standard series and is available with a separate latch and cam assembly to promote modular use.

With its customizable grip, our newest E5 Cam Latch meets the needs of multiple applications that require the same latch but with different grips, while the flexible design allows the fit to be customized to the specific needs of each application.
