The kit also contains the stainless steel cover shown in Figure 13. This cover provides additional 
protection to the sensor from weather and physical damage. Notice the cover is supplied with 4 
knockout holes to provide a variety of fiber routing configurations. The knockout holes are .88 
inch [22.4 mm] in diameter and will accept conduit fittings such as Hubbell Part Numbers 
P050NGYA.
