The K Kap.
A plastic outlet cover. For your torsion spring.
A high-visibility plastic cap that snaps over the adjustable, high-torque end of every garage-door torsion spring we touch. It does not contain anything. It is a deliberate, visible warning — so homeowners and DIYers see where the stored energy lives and keep their fingers out of it. Included free on every Kooler service.
A visible warning, exactly where the stored torque lives.
The CPSC tracks tens of thousands of garage-door-related injuries in US emergency rooms every year. A meaningful share of them come from homeowners and DIYers reaching into the torsion-spring system to make an adjustment they didn't know was dangerous. The K Kap exists because the warning the system should have had wasn't there.
A standard double-car door torsion spring stores roughly 250 to 400 foot-pounds of energy under tension at the winding-cone end. That is the side a Kraftsman winds and unwinds with bars — not the side a homeowner ever touches. The K Kap snaps over that exact end so the eye sees the hazard before the hand goes near it.
Parents put plastic outlet covers on electrical outlets so a kid sees the cover, sees that something is different about that spot on the wall, and doesn't stick their fingers in it. The K Kap is the same idea on the spring system — a visible, deliberate, plastic warning over a part of the door that homeowners and DIYers should never adjust without a trained Kraftsman on the bars.
High-visibility orange. "Danger Zone — Sealed With A K."
The cap is intentionally loud — bright orange, large readable warnings, the Kooler phone on the front. A homeowner glances up at the spring shaft and sees the cap before they see anything else.
What the K Kap is — and what it is not.
Eight straight facts to share with your spouse, your DIY friend, or anyone else who has never heard of the K Kap.
Every spring we touch. Every visit. Always free.
If a Kooler Kraftsman touches your torsion spring — whether that is a single-spring repair, a full new-spring install, or an annual Kooler Cares tune-up where we just inspect and lube — a fresh K Kap goes on the adjustable winding-cone end before the truck leaves. Every spring. Every time.
Right now the caps are 3D-printed in-house at Kooler — yes, our founder's son currently runs the printer. We are working through a supplier agreement for higher-volume production and will share the details publicly when it is in place. The material is plastic on purpose: light, safe, deliberately visible, and easy for a Kraftsman to inspect and replace on every visit.
After install, the cap is visible from inside the garage looking up at the spring shaft. Bright, deliberate, plastic — sitting right over the part of the system that stores the torque. Glance up, see the cap, remember the rule: that is not a place to put hands.
Zero. Always.
The K Kap is free on every Kooler service that touches a torsion spring. No add-on charge. No line item. No upcharge. Same Kraftsman, same visit, same Guarantee that never expires — and a fresh K Kap on every spring before we leave.
