The Stinger 310LID21V is a replacement remote transmitter engineered to work with Linear Delta-3 garage door and gate operator radio systems. Designed for fixed-code setups, it operates on the 310 MHz frequency used by the Linear Delta-3 platform and pairs with compatible receivers through DIP switch coding. This makes it a practical upgrade or replacement part for residential or commercial applications that rely on Linear Delta-3 controls, providing dependable operation for garage doors, gates, and barrier arms using that legacy code format.
Programming is straightforward: open the transmitter and set the internal DIP switches to match the code pattern in your existing Delta-3 remote or receiver, then test for proper function. This remote is not compatible with rolling-code systems such as Linear MegaCode, Chamberlain/LiftMaster Security+, or Genie Intellicode, nor with other frequencies like 300, 315, or 390 MHz. For safe operation, only control doors or gates within line of sight and verify that all entrapment protection and reversing features on the operator function correctly after programming.
