Casting Sky Handrail End Caps
Fit-Matched Tube and Rail End Caps

Handrail End Cap Selection

Casting Sky reviews handrail end cap enquiries against the actual tube or rail profile. Compare smooth round plugs, square tube inserts, knurled round caps and slotted top rail terminations to identify the connection your project requires. Match the cap face and insertion section to the approved drawing rather than relying on a similar outside size.

Send the tube opening dimensions, wall thickness, corner geometry, insertion depth and intended fixing arrangement. Include quantities and the requested finish so the selected configuration and supplied components can be confirmed before ordering.

Knurled Round Tube Insert Caps

Knurled round tube insert caps finish a round tube opening with a circular top and a textured insertion section. The visible knurled band distinguishes this family from a smooth cylindrical plug. Confirm the mating tube dimensions, insertion depth and fastening arrangement for the selected model, then coordinate the visible finish with the surrounding handrail.

  • Profile: round tube insertion
  • Detail: visible knurled insertion band
  • Fit: confirm the mating opening and depth
  • Finish: coordinate with adjacent hardware

Rectangular slotted top rail end cap with insertion features

Slotted Top Rail End Caps

Slotted top rail end caps finish the open end of a matching slotted handrail profile. The illustrated small plate uses insertion features behind its visible face. Review the complete rail cross-section, slot geometry and end condition rather than selecting by face dimensions alone. Confirm the exact cap and fixing arrangement against the approved profile drawing.

  • Profile: matching slotted top rail
  • Detail: end plate with insertion features
  • Fit: confirm the complete rail cross-section
  • Selection: match the approved profile drawing

Casting Sky End Cap Selection

Review the complete tube end before choosing a handrail cap. Round and square profiles use different insertion arrangements, while a slotted rail termination must match its own cross-section. Use the four product pages to compare the visible shapes and provide the actual profile drawing for a fit review.

State the required material, finish, quantities and included components in the enquiry. For replacement work, provide measurements and photographs of the existing opening. Keep the selected product reference with the approved hardware schedule so that future orders can be matched consistently.

Handrail End Caps

What Are Handrail End Caps?

Handrail end caps finish an open tube or rail end with a face and a matching insertion arrangement. The visible shape alone does not establish compatibility: tube wall thickness, internal corners, insertion depth and fixing method also matter. Compare handrail end caps by their actual connection. A smooth round plug has a different insertion surface from a knurled cap, while a square plug and a slotted rail termination follow different profiles. Start with the approved tube drawing and identify the intended end condition. Confirm the material, finish and supplied components for the selected model. For replacement work, measure the existing opening and provide photographs rather than choosing only by outside face size. Keep the confirmed reference with the hardware schedule so later orders can be matched consistently.

When to Review Each End Cap

Choose the product family that matches the profile, then confirm the fit and installation details:
