Aluminum Extrusion End Caps, Silver and Black, EU and CN Profile References
Non-standard custom made. Aluminum end covers for extrusion-frame ends. Choose the exact profile reference, cap shape, finish and cap-only or screw-supplied configuration. Prices are per selected cap or kit.
Materials and Configurations
- Supplier-designated aluminum caps include die-cast references and specifically listed cut-aluminum references. No single alloy grade is established for the whole range. Silver and black identify the selected appearance.
- EU and CN are supplier profile-interface references, not certifications. Square, rectangular, rounded R and special multi-hole forms are different geometries. Match the actual extrusion end, slot layout, countersink and central fixing holes.
- Cap-only options contain one cap without mounting screws. Screw options contain one cap and only the number of screws listed below. Installation views show extrusions and tools that are not included.
- Verify screw size and length, mating profile thread and countersink fit. M markings in source cap images are supplier screw references, not an assertion that the cap itself is threaded. Do not select solely from the nominal profile number.
- Original images can show nominal dimension references without tolerances. Confirm final dimensions for custom supply. No structural load rating or environmental sealing class is specified.

Original Product and Installation Photographs
Exact Model Photographs and Dimensions
Original photographs, dimension numbers and arrows are retained. CSK means countersunk-hole or countersunk-screw reference, P means hole pitch and t means thickness. Dimensions are in mm. Inches equal mm divided by 25.4, and metric threads remain metric. Images illustrate the selected reference; the supply table determines included screws.

Installation and Custom Supply
Check the extrusion end, hole positions, threaded engagement and cap seating before assembly. Clean burrs and ensure the selected screw head seats correctly without protruding or deforming the cap. Confirm tightening torque for the complete installation.
Send the selected SKU, quantity, extrusion cross-section, hole and thread drawing, finish and tolerance requirements for custom confirmation. Contact boltte@boltte.com or BOLTTE on WhatsApp.
