Rain Bird X46205 XQF101210P Purple XQF Dripline HD 1" 12" SP 100' is a patent pending product that is the landscape industry’s first pre-fabricated header for dripline installations. A Quick and Flexible replacement for a site-built header, the QF Dripline Header saves time and labor expense. Using a proprietary blend of polyethylene, similar to Rain Bird’s XF Series Dripline, the QF Dripline header allows installers to simply roll out the header and attach the dripline at guaranteed 12” or 18” spacing. Eliminating the need for measuring, cutting, gluing and taping, the QF Dripline Header saves time and money, making projects more profitable.
