Gutter Angle Connector ELKO-BIS 40x40x40 mm, galvanized, screw-fit

ELKO-BIS screw-fit gutter angle connector 40x40x40 mm is a galvanized fitting designed to join two rectangular gutter sections at a right angle. Made for 40x40x40 mm profile gutters, the connector provides a fitted corner joint that supports continuous roofwater drainage and reduces the risk of leakage at outside or inside corners. The galvanized finish increases corrosion resistance for typical residential and light commercial roofing environments.

Advantages

The connector is constructed from galvanized steel to resist rust and extend service life in exposed roofline conditions. Its screw-fit design allows secure mechanical fastening of the gutter sections without the need for welding, enabling straightforward installation and maintenance. The component’s geometry matches standard 40x40x40 mm rectangular gutters to ensure consistent alignment and a reliable joint that supports water flow through the drainage system.

Suitable for

• Joining two 40x40x40 mm rectangular gutter sections at a 90° corner
• Residential roof drainage systems
• Light commercial buildings with standard rectangular profile gutters
• Retrofit or replacement of existing gutter corner joins

When it may not be suitable

This connector is intended specifically for 40x40x40 mm rectangular gutter profiles and will not fit round, oval, or differently sized gutters. It is not intended as a structural element for supporting roof loads; it functions as a water-tight joint within the gutter system. For environments with extremely aggressive corrosive conditions or specialized finishes, alternative materials or protective coatings may be preferable.

Key specifications

• Profile compatibility: rectangular gutters with 40x40x40 mm cross-section
• Connection type: screw-fit mechanical joint
• Material: galvanized steel
• Typical use: corner (angle) joint for perpendicular gutter sections
• Environment: outdoor roofline applications for residential and light commercial buildings

How to use

Position the connector at the corner where two gutter sections meet and align the profiles so the connector sits flush inside or over the gutter ends as required by the gutter system design. Secure the connector by driving screws through the pre-drilled or marked fastening points into the gutter profiles, ensuring even tightening to maintain alignment and water-tightness. After installation, inspect the joint and apply compatible sealant if additional leak protection is desired, and check that the slope and flow are uninterrupted.

What to consider before purchase

• Confirm the gutter profile dimensions are 40x40x40 mm and rectangular in shape
• Verify that a galvanized steel finish meets corrosion resistance requirements for your climate
• Ensure screw-fit fastening is compatible with your installation method and available tools
• Check whether additional sealant or accessories are needed for a fully watertight corner

Usage recommendations

Install with appropriate exterior-grade screws and, where required, a compatible gutter sealant at the seams. Periodically inspect corner joints for debris, corrosion, and tightness of fasteners, particularly after severe weather. For long-term performance in coastal or chemically aggressive environments, consider alternative materials or additional protective coatings.
