Fulton HDPB330101 Fold-Away Bolt-On Hinge Kit for 3" x 3" Trailer Beam - 5,000 lb. Weight Capacity

Great product. The most tedious part is drilling the 16 holes. Very nice it came with its own center punch to mark the holes. After cutting off the tongue, drilling the holes are easier. But drilling the bottom holes are not easy nor comfortable with hot metal bits flying off the spinning drill bit. Yes you can protect your eyes with eye protection but unless you're wearing a balaclava as well, making this contraption to fit over your drill head will make your life much simpler. I used a deli (yogurt) container that was about 3 inches high but a 6 inch high container would have been better due to the length of the drill bits. The container contraption will capture and contain all the metal fragments making your work area much safer for you (yeah no metal splinters)The instructions recommended a four step sizes for the drill bits. I suggest going 8-10 step up to 1/2 inch especially with the bigger bits and using a heavy gear oil between drills step ups.Its easier to tighten the bolts in the back first without the front bolts in the way. BUT make sure all the bolts fit into the four holes before you start tightening the back bolts. If you have a flexible wrench head, it's easy but if not, you might have to do the back two then the front two making sure the front two bolts will fit in properly before tightening the back bolts. Yes you used a center punch and yes the holes are pretty much where they are supposed to be BUT there is still a little movement give which will make putting in the last two bolts if not properly aligned.Do yourself a favor and just buy this. It gave me another 30 inches of space which means I can get around the back of the boat without have to go all the way around the bow (or climbing over the outboard) when it's on my driveway. I'm 110% happier with the boat parking situation now

Easy to assemble and works great. Added a extra 3 ft

Exactly as described. Installed works perfectly. Let's me have an extra 4 feet in front of the trailer now.

Exactly as described and easy. I installed in less than 15 minutes. Key points are have quality saw with new blades. I used 18tpi bimetal blade and it worked like butter. Granted my trailer may not be the thickest but it is a good SeaRay trailer. Also make sure you have quality drill bits if you don't want to struggle.

Perfect fit and good quality. Easy to install.
