    OK this is directed to the guys who pulls reefers. The 4 drain holes in the bottom of the trailer (2 in front, 2 in rear). Do they make anything to plug them or what do you use to plug yours when you are trying to get down to 0 or colder on a hot day. I use paper towls to plug them but there has to be something better then that. Also if it is something that is made for it or whatever where did you get it.. Thanks guys and gals

    I thought this was another drug test thread LOL.

    With the limited reefer experience I have there should be rubber stoppers that go in those holes. The stay in until you need a wash out, sounds like yours were never replaced. Is it a company trailer?

    The ones I pull every now and then for grocery distribution account have the rubber stoppers. I will ask one if the shop guys where you can find some.

    Corks, pretty large ones, produce shippers use them for trailers hauling bananas and other fragile produce when the weather is cold.


    I have a dozen of them I removed from trailers after the load was delivered.

    The only time I've seen those holes plugged up is after a shipper put them in. They were made out of Styrofoam in a cone shape. Still not sure what theyre for. I've hauled plenty of frozen loads without the drain holes stopped up in hot weather. I guess it all depends on the efficiency of the reefer. This old POS I have now is really struggling to keep these potatoes at -10 in eighty degree weather.

    Normally used only with very cold loads like ice cream. Believe it or not, those four little holes let in a lot of hot air!
    they are available from Thermo King, trailer mfgrs. The guy that told you he never heard of them is an idiot.

    It seems the trailers with roll up doors which is what I have pulled mostly aleas have to work harder to get below freezing.

    Yeah they do let in a lot of hot air. My trailer works pretty good it will easily get down to 0 in 90+ degrees but when I haul ice cream or something that needs to be -10 it wont get down during the day. It gets down to about -8 but makes the unit run basicly continuos when its not set on that because of not being able to get down all the way. Then at night when it cools down it will get down all the way.

    What size are the holes? There are pipe plugs you can buy that are a slug of rubber with steel washers on either side of the rubber with a nut and bolt going through (available in many sizes). You use a wrench on the nut and it swells the rubber into the hole. Mcmaster Carr offers them from 3/16" to 20" diameter. Search "test plug"
