Terms of Use

Last updated: July 2026

By using this website you agree to these terms. If you don't agree, please don't use the site.

Informational site

This site describes ReCoil's work in torsion-spring development for garage doors. Content is provided for general information. We try to keep it accurate but make no warranty that it is complete, current, or error-free, and we provide it "as is."

Not engineering or design advice

Nothing on this site is a certified engineering design, a construction document, or professional advice. Any concepts, figures, or first-order calculations are for discussion only and must not be used to build, modify, or install any door, spring, or counterbalance system. See our Safety notice — this matters, because door counterbalance systems store lethal energy.

Intellectual property

The ReCoil name, logo, site content, designs, and any concepts shown are the property of ReCoil / Pain2HuStle. Certain designs and methods are the subject of pending patent applications. Nothing here grants any license or right to copy, reproduce, or use them.

Inquiries are not offers

Submitting the inquiry form, or any communication through this site, does not create an investment, partnership, employment, or contractual relationship, and is not an offer or solicitation of securities. Any such relationship would require a separate signed agreement.

Limitation of liability

To the fullest extent allowed by law, ReCoil and Pain2HuStle are not liable for any damages arising from your use of, or reliance on, this site or its content.

Governing law

These terms are governed by the laws of the State of California. Questions: [email protected].
