The Fenestration and Glazing Industry Alliance (FGIA) released an updated version of a document pertaining to roller assemblies, with or without height adjustment features, for use in sliding doors and lift and slide doors.
AAMA 906-21, Specification for Sliding Door and Lift and Slide Roller Assemblies, was last updated in 2018. “The AAMA 906 task group made quick work of an important update to capture a market trend toward heavy sliding doors,” said Matt Taylor (HOPPE North America), co-chair of the FGIA Heavy Duty Roller Assembly Task Group.
“Previous requirements for operating force considered rollers with rated weight capacities to 100 pounds,” Taylor said. “Now, roller assemblies ranging from weight capacities of 75 pounds to more than 600 pounds will be tested to proportionate levels of operating force.”
Under the updated specification, representative samples of door rollers are evaluated for performance at the weight rating specified by the roller manufacturer by cycling the rollers under load for 10,000 cycles. Clearance and operating force measurements are taken before and after the cycle test to ensure performance remains within specified tolerances.
