Dometic Elite 98401 SlideTopper Parts Diagram, Metal Cover & Brackets

Dometic Elite SlideTopper EZ 98401 has a segmented metal weathershield over its fabric roller. This model-specific parts guide separates the Elite metal-cover system from Deluxe 98001 vinyl-shield equipment, shows the main component groups, and links exact replacement brackets already listed at NewRVParts.

Verify your original model. Dometic identifies 98401 as the rail-included Elite family and 98400 as its no-rail relative. Wall bracket kits are separate. Earlier slide-topper hardware and roller assemblies cannot simply be mixed with newer replacements; use the original full model number.

How 98401 differs from nearby Dometic families

98401 — EliteMetal-covered SlideTopper with the awning rail included, according to Dometic's replacement chart.
98400 — EliteRelated metal-cover assembly without rail. The correct full assembly number remains essential.
98001 — DeluxeVinyl-weathershield topper, not the Elite metal cover. See the separate Deluxe parts reference.
9800018.401 / .40218-in mounting hardware: .401 uses the tall wall profile; .402 uses the short wall profile. Final B/U denotes Polar White/Black.

Dometic's 98-series part-number chart uses fabric colour, nominal roller length and finish within the complete assembly code. Treat the family number alone as insufficient for selecting a replacement fabric, torsion, roller or cover.

Mounting profiles, clearance and wide-unit supports

The tall .401 and short .402 bracket configurations must meet factory clearance and structural-support rules. The Dometic installation document includes separate illustrated mounting scenarios and an anti-billow reference. It specifies additional anti-billow parts and a center cradle for assemblies from 198–259 in; for 260 in or longer it additionally recommends a second cradle. These instructions do not mean every 98401 unit needs a cradle.

Dometic tall and short bracket clearance drawings

Compare the tall .401 and short .402 bracket positions against the slide-room flange before choosing hardware. These figures come from Dometic's Slide Topper installation manual for the shared 9800018 mounting-hardware family; they show installation clearances, not the Elite 98401 metal-cover assembly or its exploded parts.
