Master Lock Puck Lock, Heavy Duty Hidden Shackle Lock and Hasp, Solid Steel Lock for Vans, M736XKAD

I used this lock on a barn door outside and its not only the sturdiest lock Ive ever used/seen but it is so easy to install and use. Very happy with this lock for a sliding door application. Amazing quality.

I wish the lag bolts had security screws instead.

Straight forward installation

Muy seguro

Even though I kept the locks lubricated with lock lubricant, when the temperatures dropped into the 20s and below the locks wouldnt work.

I love these ! Very secure set up

Heavier than I thought. Although it will not stop a professional thief, it will work well for me.

Replaced the original basic storage building lock with this based off the suggestion of a locksmith. PERFECT...two wooden storage can change shape and position over time and this lock tolerates that well....unless the thief brings a serious welding machine or takes apart the door hes not getting in! I did not realize I needed very specific sized carriage bolts so take the box with you to hardware store and know the thickness of the door so you can get the accurate length. I laid out the design on the door and marked before drilling and had no problems.

Installed 2 of these on my boat to keep thieves from stealing gas and batteries, well worth the money. Installation was easy and they look nice and they are very solid. Would definitely buy again if the need arises.
