Pre-Galvanized Steel

Pre-galvanized steel parts are stamped from a sheet of steel after it has already been galvanized. The edges of the pre-galvanized parts often lose their zinc coating during the stamping process. Because of the thinness of the coating (less than 1 mil) and the fact that the edges remain exposed, pre-galvanized parts can begin to oxidize and rust quickly, so it's recommended that they be primed and painted.

Overall it has worked great. My Lowe Roughneck has ribs on the bottom. So the ribs have bracket the bunks to ride right on the trailer. This isn’t always easy on a fast flowing river ramp. The guys help center the boat.


It certainly helps guide that big heavy boat onto the trailer.
Thank you

Terry L.


Just what I needed to help guide the big boat onto the trailer


This solved the problem of the boat not sitting correctly on the trailer when trying to reload. Very sturdy. Have had this installed for a over a year and works great.


Customer service is beyond excellent. They really seem to go out of their way to make sure you’re getting the right parts the first time and are satisfied with the products you purchased.


Works great guides pontoons on trailer


Great product work perfectly on my trai lers


Awesome people and awesome product. Really gave the option I was looking for to add a longer side bunk to my trailer try to help on windy or heavy current loading.


Works okay. The brackets are flimsy and bend easily.



These guide ons are still working out. My boat is a bit heavy so I added bunks as well. Boat centers perfectly every time.


Good quality product. Good instructions. No missing parts. Easy to install. I have a 25 year old trailer that hauls a 1938 Chris Craft inboard runabout. Loading was a problem until I installed the rails to guide the boat onto the bunks.


Received and installed my bunks today. Installation of the brackets to the trailer frame was a cinch. A few measurements to get
Both side the same and off
I was to install the boards. Problem!!! Went to bolt on the brackets and there are no holes to bolt to. Bummer. Now I have to make a run to my buddies shop who has a drill press. Not hard to do, but would have been nice to know before hand. Even the picture in the instructions has the holes drilled.
All in all, got it put together.
Looking forward to trying it out. Might be a few days as the expected high is under 30 for the next week or so.



A year later!! How time flies. I have no complaints about these guides. I recently helped a friend re- install a set of bunks form another manufacturer, was surely unimpressed. The bunks sold be e-trailer are much better quality. Thanks again for all the great products. Just made another purchase this morning. My go-to for parts these days.


Works great! Fast shipping, everything is as advertised.


“A company that cares”

a 5 foot set of loading bunks or my boat trailer (rather costly). Boat and trailer at our cabin some 250 miles from home. Hauled the unopened package up there 3 weeks later. OK ! We’re ready to start assembling the bunks, with minimal tools. Problem, no holes in the brackets. We went back and forth on the phone. Then 22 miles to town for a 3/8 drill bit. Bottom line , “”I love this Company “”. Not only did they help , stick with me , and guide me through it, they also compensated, more than expected. This is a USA ten star company.
Thanks for your help and understanding.


very nice parts and they were all there so I didn't have to go to the store
would recommend this dealer and this product


I'll give it five stars only because they can't know how it will fit every trailer, but with that being said here's my pros and cons.
1. Pretty good build quality
2. Instructions are pretty straight forward
3. EVERYTHING is galvanized
4. The supplied carpet is more than enough to do both bunks.
1. The u-bolts aren't nearly long enough.
2. This will not fit a tandem axle trailer with the suggested 5' bunk board.
3. Only used the L brackets and bunk board brackets. Threw everything else away.
4. This kit will require a little bit of fabrication but it will work.

Overall if I needed another I would probably buy this again.


Parts fit my trailer as expected. Loaded my boat this weekend in a cross-wind with no issues.


The bunks worked great. Boat went on the trailer nice.... fixed my issues 100 percent.


The product worked fine after I had a piece made for the frame, the frame on boat trailer was a C channel and was narrow


Install photos


Arrived yesterday -- installed today ... everything fits ... high quality parts.



Its been a year now and these bunks have worked flawlessly. Great trailer add to make it easier to load and unload my inflatable dingy with an outboard - wind and drift are no longer a factor when loading and unloading.


Installation and fit were great, instructions were okay, but I had to look online for marine carpet installation on the bunks.


I am very pleased with this product. Installation was not difficult. And it worked like a charm; reduced the effort required to re-trailer our boat, especially in windy conditions.


Would’ve been happier if the angle iron had been pre-drilled.


Another great buy from Item showed up when promised and as advertised.


Sturdy, well-made product - just what I needed to upgrade my set-up. Adding to a lift for a pontoon boat and it is just the ticket.


Thank you for such a smooth transition.
price. Great knowledge
And a great sales person.

  • Bunk Board Guide On Kit Recommendation for Trailer with Wider Outside Frame Channels
    Since the outside frame channel on your trailer is about as wide as your boat you'd need to go with a guide on that has a 90 degree angle for the upright posts instead like the part # CE27600K90 so that you'll get closer contact like you need.

  • Availability of 90-Degree Guide Ons for Pontoon Boat
    The guide-ons we have available that are designed specifically for pontoon boats, such as the CE Smith Bunk Style Guide-Ons # CE27671, do all feature a slight angle where the board attaches. I recommend taking a look at the CE Smith 90-Degree Bunk Board Guide-On Kit # CE27600K90. This is the only 90-degree kit we have available and it is essentially designed so that you can make your own bunk board boat guide ons, specific to your particular boat. It includes two rolls of weather-resistant...

  • 90 Degree Boat Bunk Guide On Recommendation
    We have the 90 degree roller style of guide ons which would be your best option with the part # CE27600K90. This uses a roller that mounts vertically and will roll as it allows your boat to guide along past it. There isn't a 90 degree version of the # CE27660 that you referenced.

  • Are Tubes Mounted at Angle When Installing CE Smith Bunk-Style Guide-On Kit CE27600K90
    The tubes are 90 degrees, so as long as your boat trailer's frame is level and the U-bolts are properly fastened, there should not be an angle pointing upwards for the CE Smith Bunk-Style Guide-On Kit for Boat Trailers - 90 Degree Posts - Pre-Galvanized # CE27600K90. The # CE27600K90 comes with U-bolts to fit trailer frames up to 3" wide x 4-1/2" tall, but if your frame is up to 5-1/4" tall you can use the Extra-Long U-Bolt Kit # CE11416.

  • Bunk-Style Guide-On Kit for 5" x 3" Boat Trailer Frame
    The CE Smith Bunk-Style Guide-On Kit for Boat Trailers # CE27600K90 fits 3" x 4-1/2" frames but can fit your 5" x 3" framing if you get the Extra-Long U-Bolt Kit # CE11416 as well. We don't offer this kit with the longer U-Bolts automatically because the large frame you have isn't as standard so it isn't needed as often. Attached is a review video for you to check out.

  • CE Smith Bunk Guide-On's For Interior Tunnel Of Catamaran Or Pontoon Boat Trailer

The kit will include mounting hardware to attach the uprights to a 3" wide by 4-1/2" tall frame. For an I-Beam style frame like in your picture you will need 2 sets of CE Smith I-Beam Clamps # CE27682A to attach to the perpendicular I-Beam that is 2-1/2" to 4-1/2" wide.

  • Boat Trailer Guides Needed for Triple Axle Boat Trailer
    Choosing the correct guides is a little different for each boat/trailer combo but we do have a few options that you can choose from. I recommend going with either the CE Smith Bunk-Style Guide-On Kit # CE27600K90 where you supply your own 2x4 boards to fit your application, or the smaller 24" CE Smith Bunk-Style Guide-Ons # CE27660 which you could place at the front and back of each fender. These options fit frames up to 3" wide x 4-1/4" tall but it looks like you have a rather tall trailer...

The U-Bolt Kit # CES44FR will allow you to attach the upright and bracket to a frame up to 3" wide by 4" tall.

These rollers make loading and launching your boat easy. They are available in 4 and 5 foot lengths, so I've linked a page to assist. You will also need the roller bunk brackets like # DL21742.
