U Spacers height washers 2 mm, 4 mm, and 6 mm

Innovative oarlock adjustment spacers, designed for easy one-handed use.
Available in three thicknesses: 2 mm, 4 mm, and 6 mm, equivalent to one, two, or three standard washers.
One hand, easy adjustment
No more struggling, even on your own. No need to use both hands to remove a spacer! Thanks to their ergonomic design, U-Spacers can be handled easily with just one hand and stay securely in place.
They float!
Say goodbye to the fear of losing a spacer in the water. All U-Spacers float, even the ultra-thin 2 mm model.
You can head out with peace of mind.
Double security
In the heat of action, a regular spacer can come loose. Not ours! Their built-in safety catch ensures a secure fit, even in extreme conditions.
Durable and eco-friendly
Our U-Spacers are virtually indestructible: they resist wear and will last the entire lifetime of your boat, because they float you won’t lose them. Fewer replacements equals zero plastic waste in the water.
Developed with the best, U-Spacers are developed and tested in close collaboration with the French national rowing team coaches to ensure top-level performance on the water.
