This is sturdy and can be slightly altered to provide a portal for the immersion pump of a sous vide slow cooking heater. All I had was a scalpel and a #15 blade. Works great! Needn't buy polycarbonate, either, unless having something you must clean especially well to preserve crystal clear container attracts you to spend more money. Inkbird works great, by the way.I ordered this lid to go with the matching 22quart pail (Cambro 22SFSP148). The lid fits the pail but it doesn't give a solid snap to lock in place. I'm a bit concerned for the sugar I store in the pail since the lid is looses enough that bugs might be able to get through the seal. Only time will tell.It's a lid. Fits the 22 quart just fine.It fits my cambro perfectlyThe last lid I bought for the Cambro container was exceedingly difficult to put on and never sealed well since the corners never quite closed. This one is pretty loose and doesn't seal well generally. I had holed in the first lid for a fermenting airlock and bought this as a replacement without the hole.I have other Cambro round containers with good tight fitting lids. The square container lids seem to be a work in progress where you never know what the fit will be.Perfect fir with the Cambro 22SFSP148 White Poly 22 Qt CamSquare Food Storage Container. appears to be air tight and well made.This lid will fit Fit my 12 qt Camwear (the clear one) container perfectly. I cut a hole in one of the corners of the lid to accommodate my Anova sous vide devise. This was easily done with a knife and a pair of scissors.The lid I received is the blue that is pictured, not purple as others apparently received. Also of note is the fact that the sticker came off easily and in one piece by just using my fingernail to get underneath and then slowly removing the sticker. I don't know why some other reviewers have had issues with the fit, color and the sticker as I had none. Maybe the company listened to its customers and corrected these issues. If so, a thank you to the reviewers before me.It fit perfectly for the container
