In this video, Gary from Door Closers USA walks through the complete frame assembly process for theAlumitrex storefront door system. This step-by-step guide covers identifying frame components,assembling the jambs and head, installing the pivot hinge hardware, and setting the factory-notchedaluminum threshold.
Once unboxed, the Alumitrex storefront door system includes pre-engineered components designed for fast,accurate assembly:
Each component is clearly identifiable by its prep and hole patterns, making assembly straightforwardand reducing the chance of installation errors.
The strike jamb is identified by the lock strike prep and six mounting holes at the top.The pivot jamb has no strike prep and also features six mounting holes at the top.The frame head is the shorter horizontal piece and comes pre-assembled with the upper pivot hinge.
During assembly, the frame stop and weatherstripping should always face upward to ensure proper doorsealing and alignment.
The frame head slides directly into the notched ends of the jambs. Once aligned flush,the supplied frame assembly screws are used to secure the head to both jambs.The pivot hinge hardware included with the Alumitrex system ensures accurate alignmentbetween the top and bottom pivot points.
The bottom pivot assembly installs directly beneath the upper pivot hinge location.The threshold support bracket installs on the opposite jamb and provides structuralsupport for the aluminum threshold.
Both components are pre-notched for proper fit and require only basic fastening.
The Alumitrex storefront door system includes a factory-notched aluminum threshold,eliminating the need for field cutting or modification.
Countersunk holes are provided for anchoring the threshold to the floor surface.Floor fasteners are not included, allowing installers to select the correct anchorsbased on concrete, wood, or other substrates.
Once assembled, the Alumitrex storefront door frame and threshold are ready to be set into the rough opening.This system is engineered for accuracy, durability, and clean aesthetics, making it ideal forcommercial storefront applications.
