The DNT00027B Linear DT-2D remote replaces older models DT-4A, DT-4B, DT-4D labeled remotes.
The DNT00027B remote will work with Linear garage door or gate operators that use 8 On/Off dip switches to set the code. This is a brand new remote that comes from a bulk purchase pack. This means that it is wrapped in a plastic bag with no box. It comes with visor clip, battery and programming instructions. Codes are set by matching the switches to a working remote or matching codes in the receivers.
When you match the number DNT00027B on your old remote the new DNT00027B is the correct replacement remote.
