| 1 | Standard wall-mounted arms | Straight or gently angled arms for wall-mounted showerheads | Brass or stainless steel | Confirm thread type, size, and usable projection for the intended showerhead | Polished chrome, brushed finishes, or other supplier-listed options | Request a dimensioned drawing, thread details, and finish samples |
| 2 | Gooseneck and high-rise arms | Curved or elevated designs that raise the showerhead position | Brass or stainless steel | Check wall connection, arm height, projection, and clearance with the showerhead | Chrome, brushed nickel appearance, black, or custom finishes where available | Confirm the arm’s geometry and load suitability with the specified showerhead |
| 3 | Ceiling-mounted arms | Straight or extended arms designed for overhead installation | Brass or stainless steel | Verify ceiling-side connection and the required drop length | Finish options depend on the supplier’s process and product range | Check installation method, finished length, and compatibility with the ceiling outlet |
| 4 | Adjustable-angle arms | Arms with an adjustable joint or positioning feature | Metal construction; confirm the material of the arm and joint separately | Confirm the connection standard and the adjustment range | Ask which finishes cover both the arm and joint components | Request cycle-test details and inspect joint stability and sealing |
| 5 | Extended-projection arms | Longer wall arms for increased distance between the wall and showerhead | Brass or stainless steel | Check projection, thread engagement, and clearance in the installation space | Common decorative finishes may be offered; confirm availability by model | Confirm dimensions and installation requirements before approving tooling or samples |
| 6 | Compact or short arms | Short-projection arms for installations with limited space | Brass or stainless steel | Verify that the showerhead can be installed without contacting the wall | Supplier-specific finish range | Check the overall length, thread depth, and showerhead clearance |
| 7 | Decorative-profile arms | Arms with shaped, geometric, or coordinated trim details | Confirm the substrate and construction for each component | Check that decorative components do not obstruct installation or connection | Coordinate finish appearance with the showerhead and other bathroom fittings | Review a production sample for color, surface consistency, and fit |
| 8 | Stainless-steel-focused arms | Arms specified with stainless-steel construction | Stainless steel; request the exact grade and component breakdown | Confirm connection dimensions and whether threaded parts use the same material | Polished, brushed, or supplier-listed coated finishes | Request material documentation and clarify corrosion-test conditions |
| 9 | Brass-focused arms | Arms specified with brass construction | Brass; request the alloy specification and identify any non-brass parts | Confirm thread standard, dimensional tolerances, and sealing method | Chrome-plated and other supplier-listed surface finishes | Ask for material declarations and applicable market-specific compliance documents |
| 10 | Custom or OEM arms | Made-to-specification length, shape, packaging, or finish | Material selected according to the agreed product specification | Provide a drawing with thread type, dimensions, tolerances, and installation details | Custom finishes may require sampling and separate approval | Confirm tooling charges, minimum order quantity, sample approval, production lead time, and inspection criteria |
