Schroff has expanded its range of card guides for use with both sheet metal and the company's EuroPRO 19-in. subrack family. The cards feature UL94-V0 flammability, a tapered entrance to ease board installation, and positive-retention installation clips for card-guide removal and installation. Also included are 160- and 220-mm single-board computer guides and 80-mm rear transition board guides. They come in red and gray colors and fully comply with the IEEE 1101.10 and 1101.11 standards. Also available are green card guides with a 0.1-in. offset for power-supply applications. Price is $0.52 per unit, and delivery is from stock.
