Video Transcript for Master Lock Locks 2999DAT Review

Today we're going to review part number 2999DAT. This is the Master Lock Fifth Wheel, Trailer King Pin Lock. This heavy duty color will wrap around your fifth wheel king pin and the deadbolt style receiver lock right here will secure it in place. It's made of a powder-coated steel, which is durable on corrosion resistant and it is very bright red in color to provide a visible theft deterrent, and it also will remind you to remove the lock before hitching up again. This will fit most commercial and recreational fifth wheel king pincouplers. The 5/8 inch swivel head chrome-plated receiver lock will secure the color to the king pin and this pin right here can also be used as a hitch receiver lock also, we're not used as a king pin lock. Has a weather cover right here to protect the lock cylinder from any corrosion.

The swivel head design on it is easy to use even in tight spaces. The two keys are included. Just going to remove it for you and show you, put the key in, then just turn it 180 degrees. You can see that that will come off and there's your pin. The locking pindiameter is 5/8 inches.

The inside pin length of this pin, the span of it is 2 3/4inches. Now, the coupler itself, the inside width is going to be 2 1/8 inches and the total overall width, the outer width is going to be 2 5/8 inches. Now, Ido have an example of a King Pin right here. Your industry standard 2 inch size king pin. So basically, the way this would operate is you would just run this coupleraround the king pin, runyour pin through all the way to the other side, and then take your lock cylinder, go ahead and push it on, and then just turn the key 180 degrees. Once it's locked, just go ahead and pull your key right out, put the cover back over it, then you could see that it's locked into place, this will swivel. You can basically see this coupler lock is in place and nobody will be able to hook up on the king pin on your fifth wheel and tow it away.

That should do it for the review on part number 2999DAT, the Master Lock Fifth Wheel, Trailer King Pin Lock. .

great... except I had to grind the pin a little because it was hitting the kingpin and preventing it from lining up with the hole on the other side of where I inserted it. other than that.. .it is just what I wanted. Thanks 538593

My first choice in king pin locks didn't work, the wedge from the Reese Sidewinder prevented me from placing the cap all the way up/around the king pin. This Master Lock was my 2nd choice. Good visibility, easy to place, but something about the lock mechanism makes it a bit tricky to get closed. As usual, great service from eTrailer.com! 54407
