The Detex Advantex 21 HD 605 97 48X84 is a super-heavy-duty, ANSI/BHMA Grade 1 top-rod-only surface vertical rod panic exit device for compatible 48-inch-wide by 84-inch-high (4' × 7') commercial doors. It combines a single top vertical rod and deadlocking latch, No. 97 surface-mounted top strike, standard HD hex-key dogging, and premium 605 / US3 polished bright brass finish. Designed for demanding wide-stile commercial openings and paired doors where a center mullion is not desired, it provides reliable mechanical egress from the inside with a distinctive polished brass architectural appearance.
21 Series – Top Rod Only: The 21 Series operates a stainless steel deadlocking Pullman-style top latch through a surface-mounted upper vertical rod. It includes a protective stainless steel top rod cover and the specified Detex No. 97 surface head strike. Unlike the 20 Series top-and-bottom SVR device, this model is less bottom rod: there is no lower vertical rod, no floor-mounted bottom strike, no lower drop bolt, and no ramped bottom bolt cover. The one-rod configuration may simplify door and floor preparations while maintaining positive upper latching on suitable approved openings.
Additional Product Specifications and Ordering Guidance
Exit Device Configuration, Hardware Schedule and Service
Detex exit devices must be selected for the complete opening and the intended mechanical, alarm or electrically controlled function. Rim, surface-vertical-rod and top-rod devices have different strike and door/frame preparation; the full factory SKU controls compatibility.
Factory item on this listing: DTX-21-HD-605-97-48X84.
Product Selection and Installation Checklist
- Confirm door width, height, handing, stile and the designated Detex series and device length.
- Match the panic/exit device's latch and strike layout, outside trim, finish and required mechanical dogging state.
- Review the approved hardware schedule for fire-rated, windstorm, weatherized, alarmed, delayed-egress or electric-latch-retraction requirements.
- Identify any separate power supply, access-control interface, key cylinder, required mullion or outside trim needed for complete use.
- Surface vertical rod and top-rod mechanisms must match the correct head strike, rod path, floor/threshold latch as applicable, and factory device height. Do not substitute a rim device for a rod assembly.
Acceptance and Service Verification
Check smooth latch engagement, free mechanical emergency exit, authorized dogging and any alarm, electrical release, automatic-door or reset sequences specified for the exact factory model.
Factory Package and Related Components
The selected exit-device assembly and components stated for its factory SKU. Separate controllers, readers, facility keys, field wiring and installation are not automatically included. Consult the original model specifications below when matching the factory SKU to an existing opening.
605 Polished Brass (US3): The specified 605 / US3 finish is bright polished brass, not 630 satin stainless steel. Detex identifies the 605 finish as a polished-brass appearance achieved with a durable PVD surface treatment on stainless steel exposed components. The finish is suitable for commercial projects requiring a traditional polished brass aesthetic. Product photography is representative and may show a different finish; the ordered SKU calls for 605 polished brass.
HD Hex Dogging: The standard 1/8-turn hex-key dogging mechanism can hold the interior pushpad and upper latch retracted for permitted push/pull passage during occupied periods. A mortise-cylinder dogging lock is not required for HD; cylinder dogging is a different CD option. This mechanically doggable, non-fire-rated panic configuration is not the separate F21 fire-exit device. Never use this HD model to replace positive-latching fire-exit hardware on an opening requiring a fire-rated assembly.
Exit-Only – No Exterior Trim: The 21 HD 605 97 48X84 model specifies the interior panic device and top-rod assembly with no outside lever, pull, keyed entry trim, trim escutcheon or exterior cylinder. If outside access is required, select a separately specified compatible Detex 21 Series trim and appropriate cylinder/keying package. Do not assume these are included.
Features and Benefits
- Detex Advantex 21 Series: Super-heavy-duty wide-stile top-rod-only surface vertical rod exit hardware engineered for high-use commercial and institutional facilities.
- 48 × 84-inch door configuration: Nominal 48-inch device for a four-foot-wide door with upper rod assembly for an 84-inch door height.
- Top rod only: Positive upper latching without the lower rod, bottom bolt, floor strike, or lower bolt hardware of a 20 Series unit.
- Deadlocking Pullman-style top latch: Stainless steel mechanical latch engages the head strike to secure the door when not dogged.
- Detex No. 97 surface strike: Correct top-mounted strike for the 21 Series surface vertical rod configuration.
- Protective top rod cover: Stainless steel rod cover is included on 21 Series devices and protects the vertical mechanism in high-traffic installations.
- 605 polished bright brass finish: US3 premium architectural polished brass appearance, finished with Detex's PVD process.
- HD 1/8-turn hex dogging: Authorized mechanical dogging allows free passage on openings where hold-retracted panic hardware is permitted.
- No dogging cylinder: HD uses a hex key rather than the additional mortise cylinder required for CD cylinder dogging.
- ANSI/BHMA A156.3 Grade 1: High-duty mechanical panic exit standard with Detex's million-cycle-tested Advantex platform.
- UL-listed panic hardware family: Use the exact approved non-fire-rated model and follow current manufacturer installation instructions.
- Handed, field reversible: Detex commonly ships RHR as standard unless LHR is specified; confirm the door swing and approved rehanding method.
- Field-sizeable design: Size adjustments only as allowed by Detex's current instructions for the 48-inch device and 84-inch rod package.
- Patented mounting plate and strike locator: Helps align mounting and head strike to the appropriate prepared commercial door opening.
- Heavy-duty EC1 ramped endcap: Deflects damage from carts and accidental impacts in high-use facilities.
- Compatible commercial door materials: Properly prepared hollow metal, wood, fiberglass and aluminum wide-stile doors.
- No electrical components: Purely mechanical 21 HD model, without alarm, request-to-exit switch, electric latch retraction or delayed-egress functions.

What's Included
One Detex Advantex 21 Series 48 × 84 top-rod-only SVR panic exit device with HD hex dogging, deadlocking top latch, upper vertical rod and protective top-rod cover, specified Detex No. 97 surface head strike, heavy-duty ramped endcap, 605 polished brass finish, and manufacturer-standard mounting hardware.

Ordering and Installation Notes
Full model breakdown: 21 = Advantex wide-stile surface vertical rod, top rod only; HD = 1/8-turn hex dogging; 605 = bright polished brass US3/PVD finish; 97 = surface-mounted top strike; 48X84 = nominal 48-inch-wide by 84-inch-high door configuration. Verify RHR or LHR handing, head-frame strength and preparation, 97 strike positioning, door material and thickness, manufacturer requirements for independent paired-door egress, applicable building/fire codes, and whether outside trim is required. Use only fire-exit hardware certified for rated openings. The 24 lb shipping weight is an estimate pending packed carton verification, and representative product photography may depict an alternate finish.
