Size: Fenders come in different sizes to accommodate various boat trailer configurations. The size you need depends on your trailer's axle width and the size of your boat.
Mud Flaps: Some boat trailer fenders come with integrated mud flaps or splash guards. These additional features help further protect your boat from dirt and water thrown up by the trailer's tires.
Maintenance: To ensure the longevity of your boat trailer fenders, regular cleaning and inspection are essential. This helps prevent the buildup of debris and corrosion, ensuring they continue to provide effective protection.
Customization: If you have specific requirements or want a unique look for your boat trailer, there are custom fender options available. You can choose materials, colors, and designs that match your preferences.

User questions & answers

Question:	Will these fit well over 12” tires
Answer:	no sure but probably. the bracket is really for a quick release rear wheel. go to a used bike store and see if you can get a 26" hybrid or better yet a 700c size wheel and some gears.
Question:	Whats the inside measurements
Answer:	It rides no problem with one child. At least I did not notice a difference. I just used it this weekend and we had both one child and two children at different times and it felt the same
Question:	What brackets would be needed for these fenders? There is no info on what to buy? Are they universal brackets out there
Answer:	you need a QR skewer.
Question:	Do they come with mounting brackets
Answer:	No onboard storage for the wheel apparatus. You can trail the device with the handle still attached. I am sure there are inelegant ways to take the wheel and its suports with you, but I have not explored that nor does the manufacturer suggest how to do it. There IS onboard storage of the arm that connects the trailer to the bike.

User questions & answers

Question:	overall length what’s length between mounting holes
Answer:	Rounded on outside surface & flat 90 edge on inside where it gets mounted on trailer
Question:	It says 12 inch tire and also12 inch wheel what on is it
Answer:	I believe they will fit fine.. I put them on a home built with 15" tires and cut 4" off them for appearance and fit. They are strong enough to stand on if you mount them correctly..
Question:	Can they be primed and painted to match trailer colors
Answer:	These are just the round fenders as shown and mine did not come with any mounting brackets or anything like that. Our little utility trailer came with these originally and they were just welded on. We lived near the coast and they rusted out in the salt air so I plan to just get the new ones welded on and then repaint the trailer. These came unpainted so they will need some protective coating. Hope this helps!
Question:	Are these available in black
Answer:	Only one! Found that out the hard way!

Question:	Are they flexible at all? can the 29" long fender fit between a 30" spring slider? So bend 1/2" on each end
Answer:	Be careful on ordering. The unit I bought showed a light but what I received did not. It seems they 'changed' models and would refund but I had to pay to ship back. Screw them...I made the cuts, bought a couple of lights at Harbor Freight and wired them. One tip...use marine wiring if planning to launch in salt water.

Answer:	Wheel diameter.
Question:	is the wide tapered top to bottom or are the top and bottom the same at 9in
Answer:	Mine took 2 days!

Answer:	They are universal / reversable.
