For square tube plug end caps, begin with the actual tube or rail drawing. The visible face does not define the complete connection. Check the insertion section, shoulder position and surrounding finish so the cap matches the intended end condition.
Compare the delivered component with the approved model before installation. Keep the tube opening, internal corners and fixing location clear. Follow the selected product instructions rather than adapting the cap by force.
Casting Sky reviews handrail end cap enquiries against the actual tube or rail profile. Compare the visible face, insertion section, shoulder and fixing arrangement before selecting a cap. Confirm the internal dimensions, wall thickness and corner geometry from the approved drawing, then state the required material, finish and quantities.
Use the related products below to compare different end conditions. A smooth round plug, a square insert, a knurled cap and a slotted rail termination are separate configurations. Discuss compatibility before ordering rather than relying on a similar face size. Visit Handrail End Caps for the complete group.
