This is a check cover assembly for the 2 1/2 - 3" Febco 860 reduced pressure zone backflow preventers. This is to replace the earlier cover with tapped hole for test cock. Earlier versions used bulkhead fittings instead of tapped test cock holes. No special tools are required for servicing. Genuine Febco repair parts.
**Notice: The original Febco 860 and LF860 use different parts. Please be sure which model you have before ordering. The LF860 can be identified by an epoxy coated relief valve body. The original 860 had a bronze relief valve body.
