High-Security Design
The precision-engineered bullet lock mechanism provides the same level of security as the original lock supplied with your SAS New Defender wheel clamp.

The oval barrel design is specifically engineered to fit the SAS New Defender wheel clamp housing perfectly, maintaining the integrity of your security system and ensuring smooth, reliable locking operation.
Essential Replacement Part
Keep a spare lock on hand to ensure you're never caught without security for your caravan or trailer. This replacement bullet lock is ideal for replacing lost keys, upgrading worn lock cylinders, or maintaining multiple wheel clamps with different key numbers for added security. The lock number is supplied at random, and if ordering multiple locks, the key numbers provided will most likely differ, allowing you to key your wheel clamps differently if desired for enhanced security management.
Applications & Uses
Perfect for caravan owners, trailer operators, and anyone using SAS New Defender wheel clamps for vehicle security. Essential for maintaining the security of caravans on seasonal pitches, trailers in storage, or vehicles parked for extended periods. Also ideal for fleet operators who need to replace locks across multiple wheel clamps or security professionals maintaining client equipment. The bullet lock design ensures quick, reliable operation even in harsh outdoor conditions.
