There are many features and benefits to using RASCOFLEX Flexible Drops, including easy installation (which ultimately
saves you time and labour costs); this innovative design doesn't require any pipe threading, measuring or cutting. When
following the installation instructions enclosed the design prevents any installation mistakes. RASCOFLEX is easier to test
with water than other systems, as you can test the system with water before the ceiling grid is installed:
Reduces labour costs and installation time; the rate of RASCOFLEX installation is two to three times faster than
traditional fitting methods of installing sprinkler drops.
Quick Installation; RASCOFLEX eliminates the need for measuring and cutting. In case of crowded spaces, the user
can maneuverer the flexible sprinkler hose around ducts and trays.
No need for heavy/special equipment; RASCOFLEX flexible sprinkler hose comes ready to install. No cutting, welding
or threading, giving you a head start with no waste.
Easy-to-Install; RASCOFLEX flexible sprinkler drops are a fully assembled system that connects the branch-line to the
sprinkler head.
Corrosion-resistant materials by applying stainless steel 304 grade on flexible drops.
