...safety without compromise

Water stop B 15 round

Compatible with Uni 15. The water stop B 15 has two sockets for accommodating Dist K - 26 rough cut tubes with a tight seal. This prevents wet cement from entering and concreting in the tie rod. Reducing adapters are available for Dist K-22 and Dist FB-22. The 70 mm dimension becomes 125 mm if the reducing adapter is used.

Calculating of tie tube cut length (L):
LK-26 = (WD - 2c - 70) / 2

Calculating of tube cut length (L) with reducing adapter and K 22 / FB 22:
LK-22/FB 22 = (WD - 2c - 125) / 2
