Infinite Rule Security 61180-S Trailer Latch Lock for DEMCO 2-5/16in EZ Latch Stamped Coupler 2-5/8in Depth Stainless Steel

The Infinite Rule Security 61180-S is a precision-engineered trailer tongue latch lock designed specifically for the DEMCO 2-5/16" EZ Latch coupler — stamped model only. With a 2-5/8" depth and a stainless steel construction, this lock delivers a purpose-built fit that generic coupler locks simply cannot match.

Key Features:

• Application-Specific Fit: Engineered exclusively for the DEMCO 2-5/16" EZ Latch stamped coupler — does NOT fit the cast model
• Stainless Steel Construction: CNC-machined stainless steel resists cutting, prying, rust, and corrosion
• 2-5/8" Depth: Sized to fit the specific latch geometry of the stamped DEMCO EZ Latch coupler
• Weatherproof: Built to handle rain, road salt, and heavy outdoor use without degrading
• Keyed-Alike Compatible: Can be integrated into an InfiniteRule one-key system — order with other InfiniteRule locks to have them all keyed alike, or provide your existing InfiniteRule key number for future orders
• 100% Made in the USA: Manufactured by InfiniteRule Security in their own facility and inspected for quality
• Superior Deterrence: Precision fit adds greater strength and resistance to tampering compared to loose-fitting universal alternatives

The 61180-S is trusted by Airstream owners, RV enthusiasts, and professional haulers who rely on DEMCO stamped EZ Latch couplers. Unlike one-size-fits-all alternatives, this lock is purpose-built to maximize security at the most vulnerable point of your towing setup — the coupler latch.

Important: This lock is designed for the stamped DEMCO EZ Latch 2-5/16" coupler only. It is not compatible with the cast model. Verify your coupler model before ordering.
