Stronghold Hitchlock for Knott Avonride 50mm Trailer Cast Coupling Heads Including 575003, 575004, 575005 and 575008 Sold Secure Gold Standard

Great deterrent. Takes a bit of getting used to regarding fitting but looks substantial and hopefully makes thieves look elsewhere

Arrived promptly. Easy to use

Good quality and value for money, looks the part and feels really secure

This is the best quality lock for this type of coupling head.

It’s need on the trailer hitch out in all weathers for the last couple months with no sign of rust. Yellow paint is starting to fade ever so slightly but otherwise a substantial heavy weight bit of kit. If it deters a would-be thief then it’s worth the money. I think it would be difficult to remove without the proper key.

This lock is insurance approved as stated on the packaging.The materials used in this hitchlock are metallic and strong, bar the dummy ball insert, which is made of hard plastic. Previously this lock was supplied with a metal ball insert. The installation video shows a metal ball insert.The purpose of the ball insert is to stop the trailer being connected to a vehicle and it also holds the main body of the lock in position by holding the locking crossbolt behind the vertical part of the dummy ball insert . The fact the insert is plastic instead of a previously supplied metal insert, means 3 stars instead of 5 stars. Metal would be best option for dummy ball insert, sturdier, and greater peace of mind.Review based on partner's purchase of this lock from Amazon

I’ve had this lock for three months now I’m very impressed. It’s been on the trailer everyday throughout the rain and despite getting knocked about shows no signs of rust. It fits snuggly over the hitch with the lock barrel securing it in place flush so cannot be hammered or grind off. I have recommended this to friends who have purchased it and are equally impressed. Well worth the cost.
