Finished in aluminum painted (689\/US28), this kit lets facility managers quickly detach the mullion with a key, opening the full width of a double-door opening for moving large equipment or oversized deliveries. Built to Von Duprin's durability standards, the KR54 offers a practical upgrade path without replacing the entire mullion assembly. It's a reliable solution for commercial and institutional openings where flexible, secure access is required across paired doors equipped with exit devices.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRetrofit kit that converts 1654 and 4954 mullions to a key removable configuration.\u003c\/li\u003e\n\u003cli\u003eKey removable design allows the mullion to be detached for a full clear opening.\u003c\/li\u003e\n\u003cli\u003eAluminum painted finish (689\/US28) for a clean, consistent appearance.\u003c\/li\u003e\n\u003cli\u003eCompatible with existing Von Duprin 1654 and 4954 mullion installations.\u003c\/li\u003e\n\u003cli\u003eDurable construction suited for high-traffic commercial and institutional doors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFunctional Details\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe keyed removable mullion function lets an authorized user unlock and lift out the mullion using a key, temporarily clearing the center post between paired doors.
