A: The D-suffix designates a full chain drive variant, meaning chain is used for the entire rail travel distance. The A-suffix variant (GE-26966A.S) is for standard or hybrid chain/cable systems where cable handles part of the travel.
A: GE-26966D.S is compatible with PMX300, PMX500, IC250, GPS1200, Pro 0700-TR, Pro 0800-TR, Pro 0706, Pro 0800-BC, PMLD, RCD, LD, and LAD series openers that use full chain drive T-rail systems.
A: No - the D-suffix and A-suffix pulleys are distinct variants engineered for different drive configurations. Installing the wrong variant can cause improper tension, wear, or failure.
A: The pulley is positioned between the pulley bushing and the pulley bracket, where it redirects and guides the chain along the T-rail during open and close cycles.
A: Some reseller listings note 'replaces 26002B' but this appears to be a cross-reference data error and does not represent a true supersession relationship. GE-26002B.S is a pulley bushing, not a pulley.
