Capped Glass Balustrade Run | Fabrication Drawings
A straight run of frameless toughened-glass balustrade panels under one continuous metal cap rail: the top edge of every pane sits up inside the slot of a slotted round or box tube, or a nanorail, gripped in a rubber gasket, and the rail carries on over the gaps between panes. The panes are sized from the run length, a maximum pane width and the gap between panes, and stand on stainless spigots, one continuous base channel, or stainless standoff pins on the slab edge. Each end of the cap rail takes an end cap, an extension, a return to the wall or a plate fixed to the wall, and a rail longer than the stock length is joined at a gap between panes.

Frequently Asked Questions
What do I get in the drawing pack?
Each drawing pack is an A4 PDF with orthographic views (front elevation, side elevation, top view, and isometric), full dimension lines, extension lines, and a professional title block. You also get a live 3D preview in the browser and optional STEP file export for CAD software.
Can I use this drawing for fabrication?
Yes. Dimensions are computed to sub-millimetre precision from a true 3D solid model, not approximated from a template. Print the PDF at actual size, hand it to your fabricator, and build from it. Change any input and the entire drawing regenerates in about 60 seconds.
How long does it take to generate a Capped Glass Balustrade Run drawing?
Around 60 seconds end-to-end. Geometry computation runs server-side in a CadQuery process with a 30-second per-request timeout; PDF rendering and download account for the rest. If you change a dimension, regeneration takes the same ~60 seconds — there is no manual redrafting step.
Can I save and reload my dimensions for the Capped Glass Balustrade Run?
Yes. The free Explorer tier keeps 1 saved drawing, so you always have somewhere to land between visits. Fabricator saves every drawing you make and reloads the configurator in one click, so you can revise a quote, regenerate a clean PDF, or branch a design for a similar customer without re-typing dimensions.

Category: Balustrades. Tags: balustrade, railing, glass, frameless, fence-run, cap-rail. Geometry built with CadQuery on the OCCT (OpenCascade Technology) kernel — the same geometry foundation used in FreeCAD and a number of commercial CAD packages. Drawings are orthographic projections of the computed 3D solid; no view is sketched or scaled from a template.
