Use this Dometic/A&E 8500 manual patio awning visual parts guide to identify right-hand torsion, side-arm hardware, secondary rafters, roller tube assemblies and operating accessories. The product photos and part numbers below help identify separate torsion, arm, rafter and roller components. The Dometic installation drawings show how the hardware is arranged.

Identify the model and projection first. Dometic 8500 series include the 848 and 858 families, older 853/838 and Plus models, and special 7-foot-projection 841/842 systems. Do not assume roller fabrics or supporting hardware interchange between these models. Check the data tag, full awning model, exact length, finish and installation height before ordering.

Dometic factory drawings: manual awning arms and torsion

These illustrations from Dometic's 8300/8500/9000 installation manual identify the adjustable support arm, main rafter, mounting brackets and right-hand roller end cap. They show service positions rather than a complete replacement-parts list; use the manufacturer numbers and original awning model to select parts below.

Photographed 8500 service components and arm sets

Select a photograph to see the corresponding replacement part. A fabric roller tube assembly (FRTA) includes the roller and fabric, while an arm hardware set, a secondary rafter and a torsion assembly are different products.

Dometic replacement part numbers

Key Dometic MPN Component Check before buying
A 3108399.035B Standard right-hand torsion spring assembly, white Photographed exact MPN; not a heavy-duty or left-hand assembly
B 3108399.019 (finish-dependent) Standard left-hand torsion assembly Confirm the left-hand part number and finish before ordering
C 3309974.008B 44.5-inch secondary rafter, white Part-specific length; match original rafter and arm hardware
D1 8273000.401B Tall universal arm hardware set, white Manufacturer tall adjustment range 74 5/8 to 88 1/8 inches
D2 8273000.401U Tall universal arm hardware set, black Same tall geometry with black finish
D3 8273000.402B Short universal arm hardware set, white Manufacturer short range 62 5/8 to 76 1/8 inches; current store photo maps to 401B filename and is held for image QA
E 848NR16.300U Complete 16-foot 848-family fabric roller assembly Onyx/black item; not a stand-alone canopy. Select length, finish and original 848/858 family
F 940001 / 9108677537 94.5-inch manual pull strap May require the proper awning pull rod; confirm original length
G 830152.102 46-inch pull wand Accessory tool, not a replacement awning arm
H 848 / 858 family Fabric roller / canopy / torsion assembly 848 = vinyl without metal wrap; 858 = vinyl with metal weathershield; verify complete serial
I 8273000.501 / .502 (finish-dependent) Heavy-duty tall / short hardware Dometic lists heavy-duty hardware for awnings 22 feet and longer; not directly mapped to a store product
Choosing short or tall arm hardware: Dometic 8273000.402B is the short white arm set; 8273000.401B is the taller white set. These are not interchangeable based on colour or appearance. Confirm the original arm height and the complete hardware part number before ordering.

Tall versus short hardware and older-model differences

Dometic specifies tall 8273000.401-series universal hardware for a 74 5/8-inch to 88 1/8-inch adjustment range, while short 8273000.402-series hardware covers 62 5/8 inches to 76 1/8 inches. White ends use suffix B; black ends use U. For heavy-duty manual awnings 22 feet and longer, Dometic calls out the 8273000.501/502 families rather than the standard-duty 401/402. Always measure using the manufacturer's instructions.

Series Original configuration Replacement guidance
848 8500 vinyl, no metal weathershield Original full roller unit identified by 848 prefix; check length and castings
858 8500 vinyl, metal weathershield Different roller/protection configuration. Do not assume an 848 assembly matches
853 / 838 Earlier 8500 families Dometic's historical training chart describes certain equivalent 848 replacement paths; verify exact original FRTA and hardware
801 / 811 Earlier 8500 Plus families Dometic states original and replacement FRTA / hardware are not directly interchangeable. Both may require replacement
841 / 842 8500 reduced 7-foot projection Not interchangeable with standard 8-foot-projection 8500 FRTA and hardware
839 / 829 9000 acrylic / 9000 Plus Different fabric, weathershield and/or arm configurations; do not treat 8500 canopy as universal
Special compatibility warning: The manufacturer's 8500 historical reference identifies 801/811 Plus original FRTA and hardware as not directly interchangeable with the current replacement combination. Dometic also specifically says 841/842 reduced 7-foot-projection systems cannot share standard 8-foot-projection FRTA/hardware. Do not select a product just because it has 8500 in the title.

These optional products are photographed in the store but have different equipment-specific application rules. The travel latch's current listing emphasizes Sunchaser; Optima knobs are for optional Optima rafter accessories. Their presence here is for identification, not a claim that either belongs on every 8500 awning.
