FIRE PROTECTION

The Clow Medallion hydrant was designed and built to
provide unsurpassed fire protection. Utilizing computer­developed data, Clow engineers painstakingly sculpted
interior surfaces to provide the smoothest possible
waterway, resulting in the lowest possible loss of head
through the hydrant.

The result? More water to the nozzles faster. With the Clow
Medallion, it’s performance that counts.

MAINTENANCE

Extraordinary steps are taken in both the design and
manufacturing process to ensure that the Clow Medallion
can be routinely serviced and repaired easily. All working
parts are readily accessible from the top of the hydrant and

are built from the highest-quality materials.

10-YEAR LIMITED WARRANTY

The Clow Medallion carries a 1O-year limited warranty on materials and workmanship. The hydrant also equals
or exceeds all applicable American Water Works Association (AWWA) requirements. It has been listed by
Underwriters Laboratories (UL) and is approved by Factory Mutual Approvals (FM).
