Overview
Protect your trailer, caravan, RV or boat trailer from unwanted tow-away theft with this heavy-duty aluminium trailer coupler lock.
Designed for everyday security at home, on the worksite, at the campsite or in storage, this high-visibility yellow coupler lock acts as both a physical barrier and a visible deterrent. The U-shaped locking bar features 11 adjustable positions and is designed to suit compatible 50mm trailer couplings, helping create a secure fit across a wide range of towable assets.
Built from iron and aluminium alloy, the lock is made for durable outdoor use and resistance against rust, corrosion and harsh weather conditions. The tamper-resistant locking mechanism helps protect against picking and prying, while the protective rubber cap helps shield the keyhole from rain, dust, dirt and debris.
Quick to install and remove, it’s a simple way to add extra peace of mind when your trailer, caravan, RV or boat trailer is parked or unattended.
