Hinged Professional Construction Knee Pads with Non-Marking Grip and Closed Cell Foam
Product Overview
The KneePro Ultra Flex III is a professional construction knee pad that has been the industry standard for over 30 years. The articulating metal rivet hinge follows your knee as you walk, kneel, and stand, keeping the pad centered without slipping. Inside the hard plastic shell, a 5/8-inch closed cell foam pad provides sweat-resistant cushioning that holds up across full shifts. Sold as a pair.
Key Features
- Articulating metal rivet hinge keeps the pad centered over the kneecap while walking, kneeling, or standing
- 5/8-inch closed cell foam padding resists sweat, does not compress flat, and will not absorb odor
- Hard plastic outer shell extends above, below, and to the sides of the knee for full coverage
- Non-marking orange grip strip holds position on any surface without leaving residue or scuff marks
- Soft elastic woven straps with reinforced sewn ends sit above and below the knee without binding
- Quick-Snap speed clips for fast attachment and removal with no Velcro to collect debris or lose grip
- Replaceable straps, clips, and grip strips lower cost of ownership over the life of the pad
- 9 oz per pad, light enough for all-day wear across 8- to 12-hour shifts

Frequently Asked Questions
What are hinged knee pads and why do they stay in place?
Hinged knee pads for work use an articulating metal rivet that lets the upper and lower halves of the pad move independently. When you stand, the pad folds with your leg instead of sliding down. When you kneel, both halves flatten and center over the kneecap. This is why the KneePro Ultra Flex III stays in position all day without constant readjusting.
How thick is the padding on the KneePro Ultra Flex III?
The S96110 uses a 5/8-inch closed cell foam pad. Closed cell foam does not absorb sweat, so it keeps its cushioning and does not develop odor over time. If you need thicker padding with gel, the Hybrid version uses 3/4-inch triple layer foam with built-in gel packs.
Why do these knee pads use speed clips instead of Velcro?
Velcro collects sawdust, drywall dust, and other jobsite debris. Over time the hooks clog and the strap stops holding. The KneePro Ultra Flex III uses Quick-Snap speed clips with elastic woven straps that stay clean and maintain their grip for years. The straps sit above and below the knee, not behind it, so they do not bind or pinch.
Can I replace the straps and grip strips?
Yes. The straps, Quick-Snap clips, and grip strips are all replaceable. When a strap wears out or a grip strip loses traction, you replace that part instead of the whole knee pad. This is one reason these professional construction knee pads last for years in daily trade use.
Are these knee pads non-marking for finished floors?
Yes. The orange grip strip is specifically made to grip without leaving marks, residue, or scuffs on hardwood, laminate, tile, or any other finished surface. Flooring installers use these as non-marking knee pads for flooring work where surface damage is not acceptable.
What is the difference between the KneePro Ultra Flex III and the Hybrid?
The Ultra Flex III (S96110) uses 5/8-inch closed cell foam with no gel. The Hybrid Ultra Flex III (S96211) uses 3/4-inch triple layer foam with built-in gel packs. Both share the same hinge, shell, straps, and clips. The Hybrid costs more and adds gel cushioning for longer kneeling sessions on hard surfaces. The standard version is lighter on padding and preferred for general construction where you alternate between kneeling and standing.
