Southco E3 VISE ACTION Equivalents
T-handle, wing knob, tool-operated and CH751-keyed compression latches — matched to SecuriLock SL-B series by head style and grip range.
Replacing a Southco E3 or an industry-standard MS-series latch? This cross-reference maps the most-searched Southco E3 head styles to functionally equivalent SecuriLock products — same latch type, same head style, comparable grip range and materials.
How to read this table: matches are functional equivalents — same latch type, head style and application coverage. Mounting dimensions and grip ranges vary by variant. Before committing to a design, request the dimension drawing for your exact model, or send us your current part number and we will confirm compatibility.
E3 head styles → SecuriLock equivalents
Southco's E3 is a vise-action compression quarter-turn: half a turn pulls the door up tight against the gasket (IP65 / NEMA 4 rated in standard configurations). SecuriLock covers every E3 head style.

Frequently asked questions
What is the Southco E3 equivalent grip range?
E3 large-size bodies cover grips from about 11 mm to over 68 mm depending on cam. SecuriLock SL-B-2201 covers GH18–GH60. Tell us your door-to-frame distance and we'll match it.
Do you make a CH751-keyed compression latch?
Yes — SL-B-2309-100 and SL-B-2413-100 are keyed to the CH751 fleet standard, the same key system used on most utility and RV cabinets.
Are SecuriLock latches direct drop-in replacements for Southco?
SecuriLock equivalents are functionally equivalent — same latch principle, head style and application coverage. Mounting hole patterns and grip ranges differ by variant, so we provide dimension drawings and sample units for verification before volume orders.
Can I get samples before ordering?
Yes — samples are available at actual cost (sample charge plus real courier freight). Items not in stock take about 25 days. Request via the inquiry form on any product page.
