Design, height and rotation are ideal for a kitchen sink 2 vats. Installation Instructions: Supplied with a plastic clamping ring should only be used for mounting on sink (Ie no need to install directly on workplan) It is indicated maximum height of 60 mm between the clamping nut and the faucet base (plastic ring included). No minimum is indicated as this does not interfere with an installation with a sink not posed with a wrench. The thicker the sink, the lower the threaded rod spring. So once asked, it may become impossible to disassemble the valve with a wrench and it is necessary to have a hollow therefore provide key purchasing a faucet wrench if you do not have this tool. The generous length of the flexible portion with standard lengths and it's comfortable. In case of sudden interruption of the tap, no water hammer. 5 STARS largely deserved
