Yes, we do offer 20-Minute Fire-Rated doors, as a minumum, however the majority of our Fire-Rated Doors have a rating of at least 90-Minutes.
Our pre-hung door systems are engineered for maximum job-site efficiency and labor savings.
They arrive ready-to-install and include commercial-grade prep work that significantly reduces on-site labor and callback risk:
Jamb Assembly: The door slab is fully assembled and mounted within the frame (jamb) for an immediate, single-unit installation.
Hinge Mortises: All necessary hinge mortises are factory-applied to both the slab and the jamb. The hinges are pre-set, ensuring perfect alignment and swing.
Door Knob/Bore Holes: The door slab is pre-drilled with the standard 2-1/8" bore hole for the door knob/lockset, and the corresponding latch bore is cut into the jamb.
Customization (Optional): We pre-prep for specific hardware requirements when ordered in bulk. This can include specialized drilling for electronic locks or specific deadbolts, further reducing on-site customization time.
