Our elephant trunks are made of durable EPDM rubber, helping avoid the worry of cracking and dry rot due to use. The trunks are fastened to a durable ABS plastic bowl, allowing for a smooth, sure flow. The handle on the trunk itself assists in the direction and placement of the concrete flow. The Chain Connector comes standard for truck attachment. The optional Bar Connector is available upon request. Please contact us for more information! Concrete Plus & Accessories' Elephant trunks will be covered by 3 Year Limited Warranty. Includes all manufacturer errors!
