Which Type of Pan Do You Have? * 

Which Type of Inlet Port is on Your Pan? * 

If you will be connecting this Float Box to a Smoky Lake Divided Pan or Hybrid Pan, the pan’s sap inlet port is going to be a stainless steel, female fitting. Depending on when the pan was made, this fitting could be one of two lengths. Please measure it as shown in the image below. We will need to know the length to ensure that your Float Box fits up perfectly. If you have a Pan Set, select “Sanitary Clamp Fitting”.

Deluxe Sight Glass for Float Box

This Sight Glass configuration is compatible with Smoky Lake Float Boxes.

  • Solid stainless steel base
  • Anti-turbulence orifice to keep the liquid in the sight glass steady even during a rolling boil
  • The glass is fire polished and shatter-resistant
  • The scale can be placed by you to ensure the level is perfectly calibrated
  • Drainable so you don’t have to worry about it freezing overnight



Smoky Lake’s 22 gauge, mirror finish stainless steel float box monitors sap levels in your flue pan and keeps them constant. They can be mounted on any Smoky Lake pan (Raised Flue, Drop Flue, Hybrid or Flat Pans) and they come with all the applicable fittings you will need for hook up. The float box’s regulator contains five major depth settings as well as a micro adjustment for precise fine tuning. The float itself is balanced and steady. No sloppy bouncing or wobbling! Outstanding craftsmanship. Made in America.

Smoky Lake Hybrid Pans have a built-in hanger from which you can hang the float box. Whereas float boxes for Flat/Continuous Flow pans are designed to hang onto the rim of the pan. For a custom fit float box/fittings, please contact us for a quote.

Optional Upgrade: Add Deluxe Sight Glass

    Top notch keeps the level in the pan perfect. Definitely worth the money. Definitely the best float box I’ve ever used.
