Oblong square base flange for a handrail is a component designed to provide support and stability for an oblong-shaped square tube handrail. Similar to a standard square tube base flange, it typically consists of a plate with mounting holes for attachment to a surface, and a hollow cylindrical section that accommodates the end of the oblong square tube handrail. This type of flange allows for the secure installation of oblong-shaped handrails in various architectural and construction applications, ensuring a safe and reliable railing system.
