RGNL-18 Three-Linkage Sliding Door China Manufacturer Operation
The official RGNL-18 listing identifies two-track and three-track layouts for an extremely narrow three-linkage sliding door. Buyers should lock the panel travel, track width, glass notation, finish and installation interface before comparing a China manufacturer quotation.
Direct Answer for Project Buyers
The official RGNL Extremely Narrow Three Linkage Sliding Doors page lists an 18 Series system with a 110 mm two-track option and a 175 mm three-rail option. Its published opening layouts include two or four panels on two tracks and three or four panels on three tracks.
A useful quotation must show how every panel moves, which panel drives the linked sequence, where the panels park, and what clear opening remains. The page does not publish maximum unit dimensions, panel mass, installation tolerances or an order-specific test file, so these must be returned against the actual project schedule.
Use the official Sliding Doors product category for range navigation, but keep product ID 2014 on the RFQ to prevent specifications from another narrow-frame door being substituted.
Verified Quick Specs and Buyer Actions
| Item | Official Listing | Buyer Action |
|---|---|---|
| Series | 18 Extremely Narrow Three Linkage Sliding Doors | Reference the exact product page and series in the schedule. |
| Track widths | Two-track: 110 mm; three-rail: 175 mm | Confirm overall frame depth, recess and finished-floor coordination. |
| Profile | 6063-T5 aluminum | Request the proposed profile sections and identify where each thickness applies. |
| Aluminum thickness | 2.0–5.0 mm | Do not apply the full range to every section; require a marked section schedule. |
| Glass families | Tempered, double or triple tempered, laminated, Low-E, reflective and tinted options are listed | Specify one complete build-up and the required safety treatment. |
| Double-glazing notation | 5 mm + 15Ar + 5 mm | Confirm the exact meaning of “Ar,” spacer, gas fill and glass treatment in writing. |
| Surface treatments | Powder coating, anodized, wood grain and PVDF coating | Approve the process, color reference and physical sample. |
| Published layouts | Two tracks with two or four panels; three tracks with three or four panels | Obtain a numbered panel-travel drawing for the selected layout. |
Compare the Published Track and Panel Layouts
Two Tracks, Two Panels
Ask the returned drawing to identify the active panel, fixed or moving status of the second panel, overlap, handle position and clear opening. Do not infer the travel sequence from the layout name.
Two Tracks, Four Panels
Number all four panels from the agreed viewing side. Show meeting points, linked movement, parking zones, locks and the final opening width.
Three Tracks, Three Panels
This is the clearest brief for a three-panel cascading arrangement. Require each panel path, linkage sequence and three-track threshold to be dimensioned.
Three Tracks, Four Panels
Confirm which three or four panels participate in the sequence and whether any panel remains stationary. The product listing alone does not define the final choreography.
How to Select the Operating Layout
Start with the structural opening, desired clear opening, panel parking space and allowable frame depth. Then mark the interior and exterior views, panel numbers, primary handle, locking points, travel direction and required day-to-day opening position.
Coordinate the 110 mm or 175 mm listed track width with the sill support, waterproofing, drainage route, finished-floor build-up and cleaning access. Ask for a section through the head, jamb and threshold. The product page names an aluminum profile and thickness range, but the buyer still needs the offered section drawing and a written statement of the actual frame construction.
Price and Quotation Factors
Compare pricing only after every return uses the same opening and panel schedule. Main scope drivers include:
- Opening width, height and quantity
- Two-track or three-track frame
- Panel count and linkage sequence
- Clear opening and parking zone
- Selected glass build-up
- Profile sections and applicable thicknesses
- Surface treatment and approved color
- Handles, locks, rollers and linkage parts
- Threshold, drainage and fixing details
- Packaging, destination and Incoterm
RFQ Information to Send
Send dimensioned elevations and sections, structural and finished openings, quantities, agreed viewing side, numbered panel layout, two-track or three-track preference, desired clear opening, parking zone, glass build-up, finish and color, handle and lock functions, threshold build-up, drainage route, destination and requested Incoterm.
Ask Rogenilan to return the exact frame depth, profile sections, thickness by section, panel travel, linkage sequence, glass notation, included hardware functions, installation tolerances, packaging method, exclusions and required approval documents.
FAQ
Which track widths are published for the RGNL-18 three-linkage door?
The official table lists 110 mm for a two-track frame and 175 mm for a three-rail frame. Confirm the final overall frame depth and project recess from the returned section.
Which panel layouts are listed?
The page lists two or four panels for the two-track option and three or four panels for the three-track option. Request a numbered movement drawing because the listing does not fully define every panel’s travel.
What does the listed 5 mm + 15Ar + 5 mm glass notation mean?
Treat it as the source notation, not a complete approved specification. Ask the quotation to define “Ar,” glass treatment, spacer, gas fill, coating, safety marking and applicable project standard.
Can buyers assume a tested maximum panel size or performance rating?
No. The verified table does not identify a maximum panel size, applicable report number or complete test scope. Submit the project dimensions and request configuration-specific evidence where required.
Request a Panel-Controlled Project Quote
Send Rogenilan the opening schedule, panel numbering, track choice, clear-opening target, glass brief, finish, threshold details, quantities and destination. Ask for a marked return drawing tied to the RGNL-18 three-linkage sliding door.
