Couplemate trailer locks are insurance approved. All purhases can be made through your local BIAS Boating outlet at very good rates.

We recommend the CM351 to suit locking trailers with equipment. You may also like to look at the stainless shackle padlocks which are also available at BIAS Boating.

For tow vehicles that have a Hayman Reese receiver you will also need a receiver lock.

IMPORTANT NOTE: Trailer Locks are a theft deterrent and do not replace Insurance Policies. Trailer locks generally are used to deter thieves by slowing theft progress or deter then enough to give up and choose a boat trailer without anti theft devices. More boats are stolen without trailer locks than with trailer locks.
