PACLOCK’s “88-Series” is engineered specifically for trailer coupler latches found on campers, flatbed trailers, utility trailers, landscape trailers, enclosed trailers, and cargo trailers. The “U-Shaped” design and two 304 stainless steel anti-saw prevent any type of bolt cutter attack or grinding attack. The PAC-BAND keeps dirt, grime, and other elements out of your cylinder, extending the lifespan of your lock, while the PAC-Tether ensures that you’ll never lose your lock!
