The P521-09 Tank Mounting Bracket Kit is an optional accessory for use with air tanks supplied with P449-17, P449-18, P449-25, P449-34, and P449-35 Air Compressor/Tank Kits. It is used to mount the tank with the drainock at the bottom of the tank for easier draining of condensation water which may accumulate in the tank over time. One tank kit is required for mounting smaller P521-01A, 8" tanks. Two kits are required to install larger P521-04, 18" tanks.
