JR Products JFE12-A Polar White Key Lock Gravity Water Hatch

• Cut out dimension: 4-3/4-inch high x 5-7/8-inch wide
• Outside dimension: 6-1/2-inch high x 7-5/8-inch wide
• Key lock

I replaced the original which had been poorly installed by the factory. Factory had cut the hole too large. This one was just enough larger to work fine. Only had to enlarge cutout a little.

The only disappointment was it came with only 1 key.
