DO35 – DO45 Stainless Steel Bi-Lock

DO35 – DO45 Stainless Steel Bi-Lock ensures the safety of your camper or caravan when you’re not there with the ultimate coupling lock.

Stealing campers only require thieves to buy a replacement pin for $80 then hook up your DO35 coupling. The theft0 is quiet and effortless.

The Cruisemaster™ Bi-Lock assembly consists of a steel dummy pin, two keys, a lock and a dust cover.

Locks do not stop theft they help prevent theft by making it harder to steal equipment. Caravan locks are a0 deterent.

Important: Consider purchasing a hitch pin lock to replace the hitch pin on your receiver bar.

Purchase lockable chrome or stainless hitch pins here.

How does it work?

  1. The dummy pin is to be inserted into the DO35 & DO45 universal joint from the top end and the tip of the pin will protrude out at the bottom.
  2. The lock is then fitted to the protruding end of the pin and lock with the key.
  3. The coupling becomes inoperable which prevents others from being able to hitch up to your trailer or van when you are not there.

Replacement Keys

Upon receipt of your Bi-Lock, fill out the form inside to register your lock number. All keys are unique for each lock.
