No dimensions provided. No Instructions. Called store rep did not have info. This was a pain since I had to move the straps around first to figure this thing out. A simple diagram denoting strap visuals relating to the Fidlock strap slots would have saved much time and aggravation. Must be installed upside down ( Fid Logo) on my Giro to work with strap configuration on this helmet.
However, it works very well for One Hand operation once you figure it all out.

Delivery was extremely slow. Ordered on May 30,2026. Not shipped until June 3. Received June 9. Way too slow, considering the order was placed on May 30, and only going to Massachusetts.
Previously I had been very satisfied when ordering from W &S through Amazon. Since Amazon did not carry the Fidlock I went directly through W&S.
Would never buy from them directly again. W & S is fine buying from when on Amazon. Do not recommend buying from them directly online.

The clip itself seems great. Easy to use, solid quality. I thought I read this clips works with most all helmets, but could be wrong. My son’s ProTec skateboard helmet has solid straps, no break or point in the strap where you can work the current clip off or new one on. If you have a helmet like this, solid strap, then you’ll need a magnetic clip which works with solid straps.
