The Square End Cap is a stainless steel finishing component designed to neatly close the open ends of square handrail tubes or posts, delivering a clean, professional appearance while protecting the interior of the tube. Sized for 40 mm × 40 mm square tubing, this end cap prevents moisture, dust, and debris from entering the handrail, helping to extend the service life of the railing system. Manufactured from high-quality AISI 304 or 316 stainless steel, it offers excellent strength and corrosion resistance for both indoor and outdoor applications. Available in satin/brushed or mirror-polished finishes, the square end cap ensures visual consistency across modern railing and balustrade designs. Installation is quick and efficient, typically using a push-in or adhesive (glue-in) method, with no welding required. Whether you are finishing a handrail or a vertical balustrade post, this square tube connector ensures a clean, modern aesthetic with high-durability perfor

Q1: What is the main purpose of a square end cap?
A: The end cap serves two roles: it provides a visually finished "look" to the railing and acts as a barrier to keep water and insects from nesting inside the hollow square tubing.
Q2. How do I install this end cap on my 40mm tubing?
A: Installation is a simple "push-fit" process. We recommend using a rubber mallet to gently tap the cap into the tube end. For a permanent, rattle-free installation, apply a small amount of high-strength stainless steel adhesive to the internal flange before inserting.
Q3: Does this cap work with all wall thicknesses of 40mm tubing?
A: These caps are typically designed for standard wall thicknesses (e.g., 1.5mm to 2.0mm). If you have particularly thick or thin-walled tubing, please verify the internal dimensions with our technical team.
Q4: Can these be used for both handrails and floor posts?
A: Absolutely. These handrail fittings are universal and can be used to cap the tops of vertical posts or the open ends of horizontal handrails.
Q5: Is the cap removable once installed?
A: If installed with a friction fit, it can be pried off with tools; however, if installed with industrial adhesive, it is considered a permanent fixture.
