Hard-Shell Articulated Work Knee Pads
DETAILS
Hard-shell work knee pads built for workers who spend time kneeling and crawling across hard, rough surfaces. The articulated shell and shock-absorbing construction provide wearable knee coverage that stays with you as you move between low-level work positions.
- Hard-Shell Coverage: Rigid outer shells create a physical barrier over the knee area when working on concrete, decking, crawl-space surfaces and other rough ground.
- Moves With Your Work: Strap-on construction keeps your knee coverage with you while crawling or changing positions, without repeatedly moving a separate kneeling mat.
- Articulated Design: Segmented shell construction is built around a bending joint for mobile kneeling and crawling tasks.
- Shock-Absorbing Construction: Designed with shock absorption for added protection when your knees contact hard work surfaces.
- Multiple Retention Points: Wraparound straps secure the pads around the leg while leaving the protective shell positioned over the knee area.
Good For: Plumbing & HVAC technicians, construction workers and carpenters handling crawl-space, attic, installation and other repeated kneeling work.

Footwear Size Guide
For the best fit, measure your foot length (cm) and use the chart below. If you're between sizes, we recommend sizing up.
How to Measure Your Foot
- Use a sheet of paper: Place it against a wall on a hard floor.
- Stand and mark: Heel lightly against the wall, mark your longest toe.
- Measure heel to toe: Measure the distance in cm.
- Measure both feet: Use the longer measurement.
- Wear your usual socks: If you’ll wear sports socks, measure with them on.
