Can these be cut at all?
Yes you can cut to fit to size on your installation. However these do have to be cut on site, we can not do it at our location due to liability reasoning, and of course you want to measure perfectly on your site in case things change.
How do these fasten down?
This particular grating does not have fasteners, this is to make sure it meets the ADA and HEEL proof requirements. However it has a snap in place system on the edging of the grating. So if you have one of our 4 inch channels, or a 4 inch channel that you are retrofitting, then these will snap into place nicely. The snap connections can also be bent of course for a little wider connection if needed also.
