Guardian 415-3T: sectional rail kits and the correct manual
415-3T uses a separately ordered sectional rail kit, with explicit limits on other Guardian rails.
Match the model before choosing a document
Identifier: 415-3T. Keep every letter and suffix on your product label when checking applicability.
Guardian specifies sectional rail kits for 415-3T and says standard Guardian single-piece rails are not compatible.
The powerhead and rail are ordered separately. G3TKIT is listed for 7-foot doors; G3TKIT-8 is listed for 8-foot doors.
Keep the 3T suffix on support requests. The 415 manual and a general Guardian rail listing do not replace the 415-3T manual.
