    This AC-100 includes our fabricated lock, one Proven Locks 400C puck lock, and two bolts (please note you will need to use your existing nuts).

    **Optional Spacer Kit includes four custom cut, off-center spacer plates. The plates are to be installed under the locking plate (side with the puck) and are required on certain trailer configurations. Not all trailers require the use of spacers, see the images for our guidelines on typical trailer coupler setups that require the use of spacers, or contact our customer service team and we'd be happy to help! The spacer kit also comes with longer bolts to accommodate the extended span. Note that the use of spacers when not required will not affect the function of this lock, and is perfectly acceptable.
