The AMERIMAX HOME PRODUCTS 29201 is a 5-inch mill finish galvanized steel inside mitre designed for use in rain gutter systems. This component forms the interior corner joint where two gutter runs meet at an inward angle, creating a watertight connection at inside corners of a structure. It is sold in a package of 10 units, making it suited for larger installation jobs or contractor restocking. The mill finish galvanized steel construction provides corrosion resistance appropriate for exterior drainage applications. Gutter installers and general contractors are the primary trade professionals who work with this fitting.
This inside mitre is used in residential and light commercial gutter installations wherever an inside corner is present along a roofline. It is sized for 5-inch K-style or compatible gutter profiles. The 10-unit package quantity supports multi-unit residential projects or service vehicles that require on-hand inventory of common gutter fittings. Installation is typically performed as part of a complete gutter system assembly or a section replacement when an existing inside corner joint has failed or corroded.
Designed as an OEM-style replacement or new-installation fitting for 5-inch mill finish galvanized steel gutter systems at inside corner locations.
Installation is performed by gutter installers or general contractors working on exterior drainage systems. Power tools are not required, though tin snips and gutter sealant are standard for fitting and sealing mitre joints. Always apply a compatible gutter sealant or caulk to the interior joint seams to prevent leaks. Follow local building codes for exterior drainage system requirements when specifying gutter fittings.
