N5450 9" Flat Vacuum Cup with Metal Handle (91700)

9" Wood's Powr-Grip N5450 Metal Handle Plunger Vacuum Suction Cup LifterThis product is an example of why tool-lovers seek out Made-in-the-USA products. Superb quality. Simple operation. Rock solid performance. I had been using a cheaper pair of vacuum lifter's to remove and reinstall a very heavy (1-3/8" thick) Lexan deck "floor window", but grew increasingly worried that if a lifter let go, I'd either break my foot or ruin the expensive Lexan.Put two of these lifters on the surface, pump a half dozen times with that brass plunger -- and these suction cups feel like they are bolted on. Pump until the red plunger line retracts and you have the proper suction. A few more plunges will go beyond that (at least on something as tough as this Lexan).The included case is quite good -- designed to put zero weight on the cup’s rubber edge to protect it from damage. Given that the cup’s outer edge has a fairly fragile triple ridge to ensure a perfect seal, protecting said ridge while stored is important.Also, the suction cup is replaceable should that become necessary; parts are available directly from Wood's web site. (Thirty three dollars currently for a replacement vacuum cup.) Unscrew the six large Phillips screws and carefully twist the handle assembly's male tube off the rubber female cup end and lift off the plunger assembly.Given that 9" Powr-Grip lifters were about the same price as the slightly smaller and lower weight capacity 8" Powr-Grips, the 9" cups were the obvious choice. Made in Laurel, Montana, USA.

I’ve had different glass cups throughout my glazing career and this is the best hands down! Superior product! Don’t sacrifice quality to save a few bucks when buying a cup. This is the glaziers standard.

These are very high quality suction cups! They come in really nice plastic cases to protect them. We use a pair of them for installs on Prevost coach windshields and they have made installation a lot easier. We only use them for moving the windshield around once they are started in the channel but the is a lot of weight and force being exerted on them and they hold their ground perfectly as long as the surface is generally flat.

best for glazing our glass skylights

Love these for flat window glass. Been using them for about a year now and haven’t come off the glass yet.Pro tip, throw away the dumb plastic box they come in and buy the yellow fabric covers
