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.
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.

Figure 23 identifies the stop-bolt and lower arm hardware; figure 24 identifies the right-hand torsion end cap and safety lock. Spring assemblies are under stored tension and require the manufacturer's service procedure.

Dometic replacement part numbers
| Key | Dometic MPN | Component | Check before buying |

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 |

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.
