Trailer & Storage Protection / Maximum Security
Trimax Maximum Security Hidden Shackle "Hockey Puck" Trailer Lock - Steel Body
A professional-grade hidden shackle lock designed to eliminate the most common point of failure: the exposed shackle. Virtually impossible to cut, saw, or pry when used with a compatible hasp.
Part Number: DLHP 3/8" Hidden Shackle Hardened Chrome-Plated Steel
Overview
The Trimax DLHP features a unique "Hockey Puck" style that encases the shackle within a solid block of hardened chrome-plated steel. By tucking the shackle inside the lock body, there is no gap for bolt cutters to grip, providing a level of security that standard padlocks cannot match. Its "no-spring" design ensures reliable operation in freezing or corrosive environments.
R&P Service Insight
This is the "gold standard" for enclosed trailer security. If you are hauling high-value equipment or tools, a standard padlock is a target; this hidden shackle design forces thieves to look for an easier mark.
- Anti-Theft: Completely shrouds the hasp to prevent prying or sawing.
- Precision Fit: Designed to work seamlessly with hockey-puck style hasps.
- Durable Build: Weighs in at over 2 lbs of solid, hardened metal.
R&P Knowledge Hub
Compatibility: Designed for enclosed trailers, storage units, and commercial gates using hidden shackle hasps.
Vehicle / System Fit: Enclosed Cargo Trailers, Job Site Storage Boxes, Commercial Gates.
Key System: High-security 6-pin cylinder provides superior pick resistance and is re-keyable by a professional locksmith.
Performance Insight: For maximum security, pair this with a Trimax THSP2C or similar shroud hasp to ensure the entire locking mechanism is protected from all angles.
Brand & Fitment Note
Selling Brand: Trimax
Application Reference: This lock is designed for specific "hockey puck" style hasps and is compatible with commercial storage and trailer applications where the internal dimensions match.
What This Means: This listing is for a genuine Trimax DLHP high-security lock, an industry leader in trailer and site protection.
Before Ordering: Verify hasp clearance (1-3/4" wide x 1/2" tall) to ensure the lock body can seat properly over your specific mounting hardware.
R&P Maintenance Insight
While the DLHP is incredibly tough, proper maintenance ensures it lasts a lifetime, especially in harsh road environments or coastal areas.
- Lubrication: Use a dry graphite lubricant once a year in the keyway. Avoid "wet" oils that can attract grit and road grime.
- Body Care: If the chrome plating is chipped, a small dab of clear coat or rust-inhibitor will prevent surface oxidation.
- Hasp Alignment: Ensure your trailer hasp is aligned so the shackle slides through without force to avoid cylinder wear.
