Detex 03GS Night Latch Cylinder Trim for Gates with RHR Handing

Professional Gate Access Control Solution

The Detex 03GS is an optional 03 function cylinder trim specifically designed for gate applications requiring key-operated access. Operating as a night latch, this trim allows access through the activation of a rim cylinder (sold separately) and is fully compatible with Detex Advantex, Value Series, and ECL exit devices. Pre-configured for Right Hand Reverse (RHR) handing, this cylinder-only trim provides reliable outdoor access control where lever trims are unnecessary or impractical.

Professional Features & Benefits

  • 03 Function Night Latch Operation: Key-operated trim releases latch bolt with key removable only when device is in locked position for enhanced security control.
  • Gate-Specific Design: Engineered specifically for gate applications requiring simple key access without exterior lever or knob components.
  • Universal Series Compatibility: Works with Detex Advantex, Value Series, and ECL exit devices for versatile installation options across product lines.
  • Pre-Configured Handing: Right Hand Reverse (RHR) handing eliminates field configuration requirements for faster installation.
  • Commercial-Grade Construction: Detex build quality suitable for outdoor and secure entry points with high-durability materials for demanding applications.
  • Cylinder-Only Design: Trim configuration without handle provides clean appearance and reduces vandalism potential in high-abuse exterior locations.
  • Perimeter Security Integration: Ideal for fenced perimeters, courtyards, schools, and industrial facilities requiring controlled exterior access.

Detex 03GS – Frequently Asked Questions

1) Will the Detex 03GS trim work on my Advantex or Value Series exit device?
The 03GS cylinder trim is built to work with Detex Advantex, Value Series, and ECL exit devices. It is a trim only, so it mounts to the outside of an opening already fitted with one of those Detex devices. If your device is another brand, this is not the trim for it.
2) Does the Detex 03GS come with a cylinder, or do I need to order one separately?
No cylinder is included. The 03GS accepts a rim cylinder that you order separately, so budget for one in your keyway and finish when you place the order. Locksmiths keying a site into an existing system will want the rim cylinder specified to match the rest of the property.
3) Is the Detex 03GS handed, and can I use it on a left hand gate?
Handing matters here. The 03GS ships pre-configured for Right Hand Reverse (RHR), which is the handing you have when the gate swings out and the hinges are on your right as you stand outside it. It is not set up in the field for another hand, so an opening of a different handing needs the trim ordered for that hand instead.
4) What does 03 function night latch mean on a Detex gate trim?
Night latch means key access only, with no exterior lever or knob. Turning the key retracts the latch bolt so someone can pull the gate open; let go and the device relocks. The key comes out only when the device is back in the locked position, so nobody can walk off leaving the gate keyed open. Free egress from the inside is handled by the exit device itself.
5) I need a whole vertical rod exit device for a gate, not just the trim. What are my options?
The 03GS is trim only and adds key access to a Detex device already on the opening. If you are buying the device itself, ZenSupply carries surface vertical rod panic devices from other brands: the Von Duprin 8827-3FT is a Grade 1 wide stile device for 1-3/4 inch doors, the Imperial USA ED-VR531 is a Grade 1 wide stile exit-only device, and the Marks USA M9900VR is a non-handed exit-only device for a 36 x 84 opening. Note those three are exit-only or listed without outside trim, so a key-in entry function has to be specified as part of that device, not added with this Detex trim.
6) Can the Detex 03GS trim be added to a non-Detex panic device like a Von Duprin or Marks USA?
No. The 03GS is a Detex trim for Detex Advantex, Value Series, and ECL devices, and the mounting and latch interface are specific to those. If your opening carries a Von Duprin 88 Series or a Marks USA M9900VR, order that manufacturer's own outside trim rather than trying to adapt this one.
7) Is the Detex 03GS a replacement for a vertical rod exit device like the Von Duprin 8827-3FT?
No. The 03GS is the outside key trim that mounts opposite the device: it is an 03 function night latch cylinder trim that releases the latch bolt when a rim cylinder (sold separately) is turned, and it works with Detex Advantex, Value Series, and ECL exit devices. The Von Duprin 8827-3FT is the exit device itself, a wide stile surface vertical rod device in the 88 Series for a 3 ft opening with a 1-3/4 inch door thickness. If the push bar on the gate is worn out you need a device such as the 8827-3FT; if the device is sound and only outside key access is missing, the 03GS is the part.
8) The gate device is exit only with no outside key access. Do I add trim or change the device?
Either path closes the opening, and which one applies depends on the brand already hung. On a Detex Advantex, Value Series, or ECL device, the 03GS adds key entry from the outside without touching the device: it is a cylinder-only trim with no lever or knob, keyed through a rim cylinder that is ordered separately. Devices such as the Marks USA M9900VR and the Imperial USA ED-VR531 are catalogued exit only, so getting keyed entry there means going to a trimmed device rather than hanging a Detex trim on them.
9) I need key trim on a fire rated vertical rod opening. Does the 03GS cover that?
The 03GS is built for gate and perimeter openings and is handed Right Hand Reverse, and its compatibility runs to Detex Advantex, Value Series, and ECL devices. A fire rated vertical rod opening is a device decision first: the Delaney F9100 Series device (DLY-694300) is Grade 1 and fire rated for a 36 by 84 inch door, and the Marks USA M9900FVR is a fire rated vertical rod device for 36 by 84, with the MARM9900F-VR covering 48 by 84. Specify the fire rated device for the opening, then trim it within that manufacturer's line.
10) Should I use a cylinder-only trim or a lever trim on an exterior gate?
Pick cylinder-only where nobody needs to enter without a key and where the trim takes abuse. With no lever or knob sticking out, there is nothing to grab, bend, or lever on, which is why it suits fenced perimeters, courtyards, school gates, and industrial access points. Choose lever trim instead when staff or tenants need to open the gate with a credential and then use it handle-first, or when you want a dogged, pull-open condition during the day.
11) I'm standardizing gate hardware across a property. Can I put the same key on every 03GS?
Yes, because the cylinder is the keying element and it is bought separately. Order rim cylinders in a single keyway and have them keyed alike, or bring them into the property master, and every 03GS gate opens on the same key. For a property manager running multiple gates, that is the cleanest way to keep one key for the perimeter.
12) We are standardizing gate hardware across a campus. Does adding 03GS trim change the grade of the opening?
Trim and device are specified separately, and grade is carried by the device. The 03GS is a key-operated night latch trim for Detex Advantex, Value Series, and ECL devices, with the key removable only when the device is in the locked position. Grade 1 vertical rod devices in the set include the Delaney 9100 Series (DLY-692301) in stainless steel for a 36 by 84 door, the Delaney 8100 Series (DLY-8100-3684), and the Imperial USA ED-VR531 in the ED-500 Series; the Cal-Royal 9860 is a heavy duty Grade 2 exit only device. For a campus standard, fix the device grade first and let the trim follow the device line already in place.
13) Our gate device is non-handed. Does that mean the 03GS handing does not matter?
It still matters. The 03GS ships pre-configured Right Hand Reverse, so the swing of the gate has to match the trim even where the device itself is not handed. Devices such as the Marks USA M9900VR are catalogued non-handed, which means the device fits either swing but the trim mounted with it does not become swing-agnostic. Confirm RHR at the gate before ordering.
14) Is the Detex 03GS trim rated for outdoor use on an exterior gate?
It is made for gate work. Detex builds the 03GS for outdoor and secure entry points, and the cylinder-only body is what makes it hold up in exposed, high-abuse locations. Typical placements are perimeter fencing, parking entries, warehouse and distribution yards, and secured courtyards.
15) What is the difference between adding key trim and swapping to a wider device when the gate leaf changes?
Trim does not address leaf width; device length does. The 03GS is a cylinder trim for Detex Advantex, Value Series, and ECL devices and does not span the opening. Vertical rod devices are sized to the leaf: the Marks USA M9900VR is listed for a 36 by 84 inch opening and the M9900VR-48X84 for 48 by 84, and the Von Duprin 8827-3FT is a 3 ft device. If the leaf width changed, the device changes; the 03GS only decides whether that opening takes a key from outside.
