submittal 10.95. For the UL Listing, when the 48-inch/1220-mm length bracket is used with the
Series AH1-LP Flexible Hose, the maximum sprinkler K-factor is K8.0 and the maximum spacing is 30
inches/762 mm.
2 3-inch/76-mm minimum bend radius.
3 A higher number of bends may be permitted, provided the sum of degrees is equal to or less than the
total maximum allowable degrees of bends (e.g. Two 90° bends equal 180°.
Three 90° bends equal 270°). The minimum bend radius and maximum number of 90° offset (bends),
stated in these installation instructions, refer to the final installed condition of the hose.
NOTE : Differences in equivalent lengths are due to varying test methods, per UL 2443 standards. Refer
to these standards for additional information regarding friction loss test methods.
