Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the CE Smith pre-galvanized U-bolt kit for the boat trailer guide-ons. Now these are extra long U-bolts which will secure one bunk style, roller style, or a post style guide-on to your boat trailer. These are a sturdy, zinc-plated 16 gauge steel construction. They do have a nice pre-galvanized finish on them which can be primed and then painted to provide even more resistance to corrosion and to even match your trailer's paint finish. It does include one set, does include the two U-bolts and includes four of the 3/8 in size washer.
And then for the 3/8 inch by 16 size lock nuts- these parts are made in the USA. Again, this is designed to fit trailer frames up to 3 inches wide by 4 inches tall. Basically the measurements, I'll give you those. The inside measurements, we're going to measure from here to the very bottom and that's going to be right at five inches and the inside width going to measure right at 3 1/2 inches. And we did mention the diameter on these bolts are 3/8 of an inch.
But that should do it for the review on the CE Smith pre-galvanized U-bolt kit for the boat trailer guide-ons..
