The Model 1100 eye wash can be mounted directly to your faucet. The eye wash isconvenient because it takes up little space, and it provides a continuous source of water. The unit features adjustable heads and float-off dust covers for additional safety. The Model 1100 will not interfere with normal faucet use when turned off. Because this eye wash requires two motions to activate, it does not meet ANSI requirements and should only be used as a supplemental eyewash.
