Southco E3-5-15 Vise-Action Compression Latch Tubular Key Nickel Plated Steel

The Southco E3-5-15 is a replacement tubular key designed for use with Southco's E3 Series VISE ACTION® Compression Latches. Constructed from nickel-plated steel, this large-format barrel key operates the 19.1mm (0.75") tubular latch head found on a wide range of marine, RV, motorhome, camper, and trailer storage compartment latches.

Southco's VISE ACTION® system provides mechanical advantage for a tight, vibration-resistant closure that seals out water and dust in demanding environments. The key operates the latch with a single continuous half-turn motion, aligning the cam behind the frame and drawing it straight up without scraping — delivering a consistent 6.4mm (0.25") pull-up for reliable environmental sealing in gasketed applications.
