The Purpleline Saracen Hitch Lock (SHL100-2) offers reliable and robust protection for your caravan, boat trailer, camper or work trailer. Constructed from hardened, high-strength steel, this coupling lock is engineered to prevent unauthorised towing attempts with strength and simplicity.

Designed to suit standard 50mm Australian tow ball hitches, the Saracen lock provides a solid physical barrier that prevents vehicles from hitching to your trailer. Its integrated 7-pin high-security barrel lock resists tampering methods such as cutting, drilling, picking, and even gas freezing attacks. With three anti-copy tubular keys included, access is limited only to those you trust.

Key Features:

• Compatible with most trailers using a standard 50mm towball hitch
• Made from specially hardened steel for increased resistance to cutting and impact
• 7-pin cylinder lock – resists picking, drilling, cutting and freezing
• Includes 3 anti-copy tubular keys for additional key security
• Unique safety chain lock-in design – secures both hitch and chain for double-layered protection
• Quick and easy to install – no tools required

Ideal for caravans, camper trailers, boat trailers and general-purpose trailers, the Saracen is a perfect choice for securing your rig while parked at home, on-site or at a storage facility. Its bright finish also acts as a visual deterrent for opportunistic thieves.

Installation Tips:

• Ensure the coupling head is clean and aligned before locking
• Slide the lock into place over the coupling and engage the locking barrel
• Utilise the safety-chain securing design by threading your trailer chain through the designated locking slot
• Keep a spare key in a secure, separate location
