  • Cou­pler Locks: Cou­pler locks are designed to secure the trail­er’s cou­pler, pre­vent­ing unau­tho­rized access and deter­ring theft. They typ­i­cal­ly fit over the cou­pler and use a lock­ing mech­a­nism to secure it in place.

  • Wheel Locks: Wheel locks immo­bi­lize the trail­er by pre­vent­ing the wheels from rotat­ing. They are high­ly vis­i­ble deter­rents that make it chal­leng­ing for thieves to tow away the trail­er. Wheel locks often come with adjustable siz­ing to fit var­i­ous wheel sizes and fea­ture robust lock­ing mech­a­nisms for added secu­ri­ty.
  • Hitch Locks: Hitch locks secure the trail­er’s hitch to the tow­ing vehi­cle’s hitch receiv­er, pre­vent­ing unau­tho­rized detach­ment. They are easy to install and act as a strong deter­rent against theft.

  • Pad­locks and Hasps: Adding addi­tion­al secu­ri­ty to your boat trail­er can be achieved by using pad­locks and hasps. They pro­vide an extra lay­er of pro­tec­tion by secur­ing doors, stor­age com­part­ments, or oth­er access points on the trail­er.
