The 830-19 hinge with the included spacer is a direct fit replacement for the 830-40 hinge.
Complete Hinge - Grass 830 Hinge and 830-19 mounting plate - Nickel Finish - Refurbished - Springs are good and the action is smooth. This is a complete hinge. Screws and spacer are included.
What does "Refurbished" mean to me? These hinges arrive to us from various sources and in various conditions. We separate the usable from the unusable. The springs and pressure pins are salvaged from the unusable hinges. The usable are cleaned in a solvent with rust inhibitors and inspected for operation. Springs and pressure pins are replaced as needed. A high quality grease is applied to pivot pin, pressure pin and spring ends. The hinges are tested again for operation before final approval.
