Detex Gate Cylinder Trim | Function 03 | Standard Silver/Gray Finish
Add an outside key-operated access point to a properly configured gate with genuine Detex 03GS Function 03 Cylinder Trim. The 03GS is a compact, surface-mounted gate cylinder-trim housing with a circular opening for an operating rim cylinder. It is an optional accessory for compatible Detex Advantex, Value Series, and ECL gate exit-device installations. The standard finish is silver/gray to coordinate with Detex gate hardware.
Additional Product Specifications and Ordering Guidance
Exterior Trim Compatibility, Handing and Keying
Detex trim components are selected by the exit-device series and exterior door function. Exit-only plates, dummy pulls, keyed pulls and classroom/storeroom levers have different operating purposes; correct appearance or finish is not proof of mechanical compatibility.
Factory item on this listing: DTX-03GS.
Product Selection and Installation Checklist
- Match the original Value Series or Advantex trim template, wide/narrow stile, lock function and outside-door preparation.
- Check the required handing, finish, handle/plate size, door thickness and attachment centers against the approved hardware schedule.
- For keyed or lever functions, verify appropriate rim/mortise cylinder or interchangeable-core housing and whether core and keys are furnished.
- Select the exact variant SKU; do not assume a left-hand lever, classroom function or narrow trim can replace a right-hand or wide-stile part.
Acceptance and Service Verification
Check outside trim operation in its specified locked/unlocked state, key function where applicable, positive latch engagement and free exit from the inside.
Factory Package and Related Components
The selected exterior trim/plate component as packaged by Detex. The panic bar and cylinders/keys are separate unless the factory model specifies otherwise. Consult the original model specifications below when matching the factory SKU to an existing opening.
Function 03 — Key Retracts Latch: In a compatible installation, an authorized key in the properly installed rim cylinder operates the corresponding exit-device latch-release mechanism, enabling outside entry. The gate's inside exit device provides the required egress function. Rim cylinder and keys are required but are NOT included. The 03GS is the cylinder-trim housing only, not a complete keyed lockset, exterior pull handle, exit device, or full gate plate kit.
Features and Benefits
- Genuine Detex 03GS accessory: Specifically designed as optional Function 03 cylinder trim for gate applications using compatible Detex exit and exit-control hardware.
- Key-operated outside access: Provides a dedicated cylinder mounting location for a separately supplied operating rim cylinder, allowing the key to release the latch in a correctly configured gate installation.
- Compact gate-mount housing: Small approximately 2 in. × 2 in. × 2 in. external block-style cylinder trim, as illustrated in Detex's gate-accessory dimensional drawing. Verify exact clearances and installation template.
- Standard silver/gray finish: Coordinates with Detex's silver/gray gate-plate accessories. Detex also offers a black -BLK option as a separate catalog configuration; this listing is for the standard 03GS, not the -BLK model.
- Multiple compatible Detex families: Listed for use in supported Advantex, Value Series, and ECL gate hardware assemblies; confirm the exit-device and cylinder-actuation setup for your gate.
- Works with gate accessories: Designed to integrate into properly specified gate arrangements that may use Detex GTPL adjustable gate plate, GTPLGRD latch protector and GTSTKBKT strike receiver bracket, as applicable.
- Rim-cylinder application: Uses an operating rim cylinder, sold separately; do not order a mortise cylinder as a direct substitute without Detex confirmation.
- Service and retrofit use: Suitable for new gate installations or replacement/repair of compatible existing Detex 03GS outside-cylinder trim.
- Exterior access and safe egress: Supports controlled entry from the pull side while the appropriate inside device provides the exit function, subject to correct fabrication and local requirements.

What Is Included
One Detex 03GS Function 03 gate cylinder-trim housing in the standard silver/gray finish, plus any standard mounting components actually supplied in the factory package. Refer to Detex's current packing list for exact fasteners.
Not Included
Operating rim cylinder, keys, inside panic/exit device, complete latch or strike, adjustable gate plate, GTPLKIT, gate latch protector, strike receiver bracket, additional mounting hardware, gate, fence, and installation labor are not included unless separately ordered. The cylinder hole does not mean that a cylinder is included.
Ordering and Installation Notes
This model is the standard gray/silver 03GS. If a black-finish cylinder-trim housing is required, order the separate 03GS-BLK configuration rather than assuming the standard SKU is black. Confirm the operating rim-cylinder model and its tailpiece, exact Detex device family, gate and fence-post clearances, selected gate plate or mounting arrangement, and available space on the pull side before purchase.
Function and safety: 03GS is a small cylinder housing for gate use, not the wider Detex 03C/03CN door pull trim. Detex's standard gate hardware illustrations are for rim-exit applications; surface-vertical-rod gates may require additional fabrication. Verify positive latching, fire/egress requirements where applicable, accessibility and the local authority's requirements for the completed gate assembly. The 03GS housing alone does not provide emergency egress.
