It easily positions the sprinkler in center of the ceiling tile at a correct height. Installation can be done in 10 to 15 minutes and does not require any special preparation. The flexible drop system is a complete unit in itself which includes a corrugated stainless steel flexible drop with nipple, reducer, square bar and brackets, which are fitted to the ceiling tile support rails to locate and secure the sprinkler in correct position. Not only does this reduce installation time but also makes the installation process a ‘mess-free’ activity by eliminating cutting and threading activities on site. The structure of threaded connection of the fitting is a limited thread (which cannot be over-tightened), and the packing seat at the Reducer and Nipple is tapered to 45°. This prevents leakage caused by damaged packing due to over tightening by an unskilled installer.
