A drawer that tips, jams or pulls right out of an RV cabinet may not need an entirely new slide assembly. It could have a cracked rear socket, a worn roller guide, a loose bracket or a damaged rail. This guide helps identify what actually failed and then match the original component by mechanism, part number and dimensions.
Where does the drawer fail?
Recognize the original drawer slide system
Paired side-mounted rails
Two track assemblies, one on each side. The RV Designer D412, D414, D418, D420, D422 and D424 family uses paired ball-bearing slides.Single track and rear socket
The track seats inside a socket at the rear of the cabinet. Match the track-opening cross-section, socket depth and attachment before replacing it.Conceptual mechanism symbols are for recognition, not manufacturer drawings or mounting specifications.
Measure the rear socket opening, not just its outside
JR Products lists three adjustable drawer socket designs with different track openings. The opening measurements below are width × height; socket depth is shown separately.
| Exact part | Opening profile | Track opening | Socket depth |
|---|---|---|---|
| JR 70715 | Question-mark profile | 0.375 × 1.090 in | 2.125 in |
| JR 70725 | Small C profile | 0.375 × 0.850 in | 2.125 in |
| JR 70735 | Large C profile | 0.437 × 0.980 in | 2.375 in |
RV Designer slide lengths for full-rail replacements
When the rails themselves are worn or bent, compare the removed assembly with these D-series lengths. This family consists of paired 45 mm ball-bearing full-extension slides, but an exact replacement also requires matching the mounting method and available side clearance.
| RV Designer part | Slide length | Mechanism | Package |
|---|---|---|---|
| RV Designer D412 | 12 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
| RV Designer D414 | 14 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
| RV Designer D418 | 18 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
| RV Designer D420 | 20 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
| RV Designer D422 | 22 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
| RV Designer D424 | 24 in | Full-extension ball-bearing, 45 mm | Two slides / one pair |
A nominal 22-inch slide, for example, is not automatically interchangeable with the JR Products 70995 repair kit, even though the latter also refers to 22 inches. The 70995 specification describes spacing between track mounting holes on a different type of drawer system.
Matching drawer components and product photos

Drawer repair kits
Before fitting a new socket, guide or rail
Remove the drawer according to its track system and inspect the rear support surface, old screw holes and drawer box for damage. Measure the track and socket opening with the parts separated, and confirm that the drawer can travel smoothly without scraping or binding after reassembly. Avoid assuming that different repair kits include the same parts.
For eligible used parts, viewing and pickup in Kelowna are by appointment. Check the individual listing and arrange a visit before arriving.
