About BlackDiamond Rubber
BlackDiamond has quickly become a top choice among window cleaning professionals worldwide. Founded by Casper Schjorring of Denmark, the brand has seen consistent month-over-month growth since launch and is now sold in over 15 countries — with global expansion ongoing. Casper remains hands-on in the business, continually refining both his products and manufacturing processes to stay ahead of the industry.
One of BlackDiamond's standout innovations is their double-molded squeegee rubber: a process that fuses two pieces of rubber together to shield the blade's sharp edge from damage before it ever hits a window. This construction keeps the edge factory-fresh right up to first use. BlackDiamond also developed a proprietary method for achieving a consistently straight edge, ensuring a clean, streak-free pull every time.
BlackDiamond soft squeegee rubber is available in sizes ranging from 12 to 40 inches, and comes in both round top and flat top profiles to fit a wide range of squeegee channels.
Real Customer Reviews:
"The BlackDiamond rubber is unmatched! I was using the facelift red razor for a while and it was good. It had a long life and super durable. But I found it linked really badly, and didn't always do the best job of removing the water from the windows. It was sticky and hard to maneuver during pole work. The BlackDiamond rubber fixes all those issues. It's super smooth has a decent lifetime, durable, and glides across the glass like no other. I'm actually finishing route jobs faster as I'm not spending as much time touching up and I can move faster while squeegeeing! 10/10 would always recommend!"
"Good rubber, good price. I have used a couple of different rubbers, and I always come back to this one. My biggest concern with rubber is how quickly the tips tear. I do trim the tips, but the more you trim them, the more finishing you have to do. BlackDiamond rubber has pretty good longevity."
"I'm overall very impressed with this product. It does as it claims; has a very sharp edge and works very well with very little pressure."
"I've used this rubber for the last 4-5 years, and this is the best, most inexpensive rubber out there! If you haven't tried BD rubber, do yourself a favor and try it."
"It’s a great rubber for any channel, easy to customize and good for every temperature I’ve used it in."
