D & M Manufacturing, Inc. SENTRY Backflow Theft Prevention Products D & M Manufacturing, Inc. Cages simply cover the problem but do not protect it.

products are designed (Patent pending) and developed for specific security applications and are American Made. It is and will continue to be our goal to lead in innovation and development of security products to protect your property from the growing theft problems. Brass and Copper are increasing in value and that will contribute to the ever increasing threat to your property, damage as a result

of theft, disruption to your business along with the high cost of replacement associated with the loss. We set out to keep Sentry Products simple by designing for strength, aesthetic appearance, simple installation, and affordability. Sentry Products lock it down, lock it up, lock a valve on or lock a valve off.
