Specifications: Pop-out handle cylinder lock engineering with security in mind used in vending machines. Available with the standard spring bolt style or with our Patented spring loaded dead bolt style where it functions as a dead bolt in the locked position, but is spring loaded in the unlocked positions.
Material: Zinc die cast housing and cylinder with hardened stainless steel guides. Zinc die cast bolt is standard, Stainless steel bolt is optional.
Mechanism: Available in triple bitted 14 or 17 tumbler Duo type "M" mechanism with optional registered keying system. Lock uses two internal body lugs which resist pulling, and hardened stainless steel head and body guides to resist drilling. On the UL recognized version, the lock mechanism is enhanced by even thicker body lugs for better pull resistance as well as a stainless steel drill plate in the back of the lock preventing access through the lock to the bolt. This version does utilize the stainless steel bolt as standard.
Operation: 125∞ key turn. Key withdraws in locked position only.
Finish: Bright chrome is standard ≠ other finishes available upon request.

Also available: Part number D8714 tubular inner cylinder.

High Security Duo Mechanism - Features

  • Plug body material is zinc Zamak (#3), hardened stainless steel head guide to deter drilling, tumblers and body key guides of spring tempered brass.
  • A practically pickproof mechanism employing fourteen tumblers, consisting of two sets of five primary tumblers, and one set of four secondary tumblers.
  • Non-duplicatable keys for controlled replacements.† Duo keys have three cuts, the two opposing cuts controlling the two sets of primary tumblers, and the side cut operating the four secondary tumblers, not duplicatable on standard machines.† Key blanks are controlled, sold only to original equipment manufacturers and their authorized agents.† Special restricted codes are provided if requested.† These code numbers will be sold only to the original owner.
  • Freedom from lock failure because of dirt, freezing, or corrosion is assured.† Positive tumbler operation for unlocking is accomplished by a design which provides for mechanical movement of the tumblers without aid of springs.
  • Long wearing qualities.† Duo mechanisms "M" has one hard stainless steel guide and four spring tempered brass key guides which provide precision bearing surfaces for the key and thus assures perfect tumbler alignment without the loss of pickproof qualities and key interchanging characteristics for not less than fifty thousand operations.
  • Standard Duo mechanism offers 13,950 primary combinations, and 240 normal master changes, more could be provided if required.† Master keying of a Duo lock does not degrade the security of the lock, as the master key operates on its own independent surface on the tumbler.† (Pin tumbler locks are master keyed by splitting the pins and therefore lowering the security of the lock.)
  • For additional security against drilling locks they can be made with hardened stainless steel head guides plus 4 hardened stainless steel body guides.
  • Standard brass keys can also be made in a durable nickel silver material.† Nickel silver has long wearing qualities that are useful when a single key is opening many locks.
