|A 3.5 gallon disposable plaster trap that can be installed under the sink in the dental lab or dental office to prevent plaster and sand from clogging the plumbing. Our trap features durable, leakproof seals which can be reused. Just snap them out of the old trap and snap them into a new plaster trap lid. It is compatible with the common 1.75 o.d. flex hose (sold separately). The bucket is semi-transparent, so the level of plaster can be easily seen. The size is 11.25 tall x 12 diameter. Made in USA. Note: Due to the size and/or weight of this product, only 1 can be ordered per box. If you wish to order more than 1 then please call us to place the order. These can be shipped without the lids put on, so several can be packed in 1 box which will require the lid to be hammered onto the bucket.
