Tool: Wood’s Powr-Grip N4950 – 8″ Flat Vacuum Cup with Metal Handle
The Wood’s Powr-Grip Vacuum Cups are top-notch, American made, quality tools. It’s funny that I think of certain tools as ‘beautiful’ and say I ‘love’ them. My pair of N4950’s are beautiful! Though I may baby them and oooh and aaah over their quality, I stake my safety to their performance on the job.

My second job, last year, requiring Vacuum cups was a 31 window upgrade on a Modern home resembling The Glass House. The finished glass panels were 6 feet square, 1″ thick and heavy as sin. The weather ranged between 15º-30ºF; at times snowing. Oh the joys of a being a builder. Using my beautiful Wood’s Powr-Grips we were able to safely manuever the monsters around the house and into place.

On a previous job, these Vacuum Cups handled 4′ x 4′ skylights safely to a rooftop on the back of one very strong fellow. I put the safety of my materials and my men in the good hands of Wood’s tool quality.

Working with glass is a regular part of Home Building. Safety is paramount when working with large sheets of glass. Reminding carpenters to remove their tool-belt when carrying glass panels is important, keeping your vacuum cups clean and protected from debris and damage at all times is critical. You don’t want foreign material, including small dust or dirt particles, between your glass and the soft rubber cups. This is one tool that doesn’t lie around on my job. I put them to use and put them away. …and yeah, I love these!

Note: I lucked out. Needing vacuum cups for a large job, I asked my local glass shop to order me “two of the nice ones” from their supplier. Not knowing what to expect, I was very happy to find I’d purchased a pair of Wood’s Powr-Grip N4950 – 8″ Flat Vacuum Cup with Metal Handle!
