FAQs
What is a mullion, and why use one instead of vertical rod exit devices?
A mullion is a removable or fixed post installed between a pair of doors so each leaf can carry its own independent rim exit device rather than needing surface or concealed vertical rods. The PDQ 9300 is a removable mullion designed to work with 6300R and 6400R rim devices, letting each door latch into the mullion instead of into rods running inside or across the door face.
Can the 9300 mullion be removed to open up the full doorway?
Yes, it's designed for easy removal from the top bracket using a rim cylinder, converting the pair into a single unobstructed opening. This is useful for moving large equipment or furniture through an opening that normally functions as two separate egress doors.
Is the 9300 mullion fire-rated?
Yes, it's 3-hour fire labeled for door pairs up to 8' x 8' when used with fire-rated 6300RF/6400RF rim devices, is ETL listed, and includes the 639080 strike required for fire-labeled installations.
What lengths does the 9300 mullion come in?
It's available in 8' or 10' lengths and can be field-cut shorter to fit the specific door pair height, giving installers flexibility without needing a custom factory order for non-standard opening heights.
What is the 9300 mullion made of?
Cast stainless steel head and foot brackets support a powder-coated 2" x 3" steel tube with 3/16" wall thickness, finished in 689 aluminum, which can also be field-painted to match surrounding frame color.
When should I use a mullion instead of the 6300V or 6300C?
Choose the 9300 mullion with two rim devices (6300R/6400R) when a visible center post is architecturally acceptable and a simpler, lower-cost latching setup is preferred over vertical rods. Choose surface (6300V/6400V) or concealed (6300C/6400C) vertical rod devices instead when the opening must stay mullion-free for a fully unobstructed doorway.
