Replacement cover locks

Hello all,
I bought my tank second hand and it only came with one lid lock. I've been scouring the internet for a replacement, but haven't found one's that are big enough. I bought some that say they will fit most tanks 30+ gallons, but are still too small for mine. Any suggestions on where to find a replacement? The dimensions of my terrarium are: 18 " deep, 21" tall, and 48" long. Thanks in advance!

Well is it a tank or terrarium? If it's a tank any local pet store should have them in the aquatic area where the tanks are

Post a pic if you can of the one you have. Then check Ebay.



Good luck!
