Kinlong 250HA Point-Fixed Glass Curtain Wall Spider
250 mm stainless-steel spider for point-supported glass curtain walls
Overview
The Kinlong 250HA is a 250 series multi-functional spider for point-supported glass curtain walls, produced by precision casting and then machined and polished to a satin or mirror finish. Its published dimensions give an approximate 250 mm hole centre distance, a 29 mm seat height and an M30×1.5 centre bolt hole, with material options of CF8, CF8M or CD3MN stainless steel. The spliced arm design allows the hole centre distance and arm/base angle to be adjusted on site, so the fitting suits diamond-shaped and other irregular glass layouts as well as canopies and skylights.
