I received a catalog from Harry Falk company yesterday and they offer a new rubber blade called “Double Rubber”. It’s a blade that has 4 usable sides. If it works well it’s got to be a money saver because you get twice the use out of a single blade. It can only be used in channels.
Anybody used any of this yet?
I may give it a try in my 18 inch channel.
Heck, if it is good rubber and lasts I may even go back to using channels in smaller sizes just to save money on rubber blades.
