Just What I Needed
Purchased this in order to be able to lock a shed with a very thin locking mechanism, after no other lock seemed to fit. Sturdy and well made. Well worth the money.

Great
Very good. But stupid I had to get one of these to be able to lock my shed door. The design for the shed lock is dumb but this works on it

Fits Keter sheds!
This is perfect to use on Keter sheds (like the newer Darwin model) with the small lock holes. Even small padlocks struggle to fit the lock space, but with this device you can use any lock you desire!

Just right for multiple padlocks for one box
Never used one of these before, but was after something for an escape room puzzle box where I can lock a box using more than one padlock. This is just the thing for it - seems robust and the size of the holes seems spot on for standard padlocks.

Got these for added layer of security
I got this as a added layer of security for bike cover on motorhome just enough space for the four steel eyelets to be locked together making it harder to remove cover with out cutting off, anything to help slow them down

Versatile equipment
Works very well to allow use of a padlock on a gate with limited access to the hasp in the drop bar lock.

J'adore !
Produit conforme à sa description, ni plus ni moins. Les trous sont assez gros pour pouvoir y mettre tous les cadenas que l'on souhaite

Perfecto
He hecho un break out con eso y me ha ido perfecto para poner todos los candados necesarios.

Gutes, stabiles Teil
Ist für meinen Zweck gut geeignet. Ich habe einen Schrank, der mit einem Vorhängeschloss verschlossen werden sollte; die einigermaßen stabilen Schlösser hatten jedoch eine zu großen Bügel und es war immer eine Riesen Fummelei, das Vorhängeschloss einzufädeln. Mit dem Masterlock ist es sehr einfach und für mein Empfinden genauso sicher wie nur mit Vorhängeschloss.

Just what was needed
Worked perfect for the game we created, while they had to find the right keys for multiple locks.
