The Plain Round Aluminum Elbow is a vital component in residential and commercial rainwater gutter systems, designed to efficiently redirect water runoff from the roof to designated drainage areas. With a precision-formed 75º bend, it helps ensure that rainwater is diverted safely away from building foundations, landscaping, and erosion-prone areas-protecting both structures and surrounding environments.
Fabricated from .024" (0.6mm) thick 3003 alloy aluminum, the elbow offers excellent durability, corrosion resistance, and long-term performance. A baked-on enamel finish not only enhances its weather resistance but also adds to the clean, professional appearance. For aesthetic consistency, the elbows are available in a range of colors to match most gutter systems, making them suitable for both new installations and retrofits.
Typically, two elbows are used per downspout to create a smooth transition between the gutter and the drainage system. The optimized angle of the bend supports effective water flow and helps minimize the risk of blockages.
These elbows can be integrated with other drainage solutions such as PVC emitters, catch basins, Flo-Well systems, or pop-up drain components-allowing water to be safely released in appropriate zones such as curbs, gardens, or stormwater areas.
For insulated piping systems or enhanced weather protection, optional aluminum elbow covers are also available. These covers, made from the same high-quality aluminum, offer added benefits including:
Resistance to corrosion, fire, and salt spray
Durable structure that maintains integrity even after impact
Easy assembly and disassembly for reduced installation time
Reusability and low maintenance, contributing to energy savings and environmental protection
A waterproof, anti-fingerprint finish that stays clean and professional-looking
With its durable build, easy installation, and proven performance in diverse weather conditions, the Aluminum Elbow for Rainwater Gutter Systems is a practical and high-performing solution for effective rainwater management.

a. Cleaning and Quality Check
Ensure each rainwater pipe connector is thoroughly cleaned and inspected. Remove any production residue or dust, and confirm there are no visible scratches, dents, or structural issues.
b. Grouping and Bundling
Organize connectors by size and design.
Stack or nest them efficiently to reduce movement and save space.
Bundle tightly using zip ties or strapping, without applying excessive force that could distort the product.
c. Surface and Edge Protection
Wrap each bundle with bubble wrap or foam padding to guard against shock and vibration.
Reinforce vulnerable areas (especially edges and outlets) with corner guards or additional padding.
d. Final Wrapping
Use stretch film or shrink wrap to secure the entire bundle, ensuring all connectors remain stable and protected from moisture or dust.
a. Clear and Durable Labeling
Apply water-resistant, easy-to-read labels to each package.
Include handling instructions such as "Fragile," "This Side Up," or "Do Not Stack" to avoid damage.
b. Strategic Loading
Position the packages flat and supported during loading to prevent bending or misalignment.
Avoid placing heavy objects on top of the connectors.
For longer or irregularly shaped connectors, ensure appropriate tie-downs and padding are used to minimize shifting during transport.
c. Pallet Use for Bulk Orders
For large shipments, stack bundles evenly on a stable pallet.
Use heavy-duty strapping and shrink wrap to secure the load.
This method helps ensure safe, efficient transportation-especially with freight or long-distance carriers.
