## Description

LARGE REPLACEMENT BULB FOR DOUBLE BELL HORN delivers extraordinarily loud honk. FITS THESE HORNS: Hard-to-find "Long Tube" bulb fits Dobani bulb horn product code "BULD" and various vintage double bell horns. Bulb does not fit Mini (bicycle size) horns. EXTENDS LENGTH OF OTHER BULB HORNS: Want to add a few inches to your other bulb horns? Although designed for the Double Bell Horn, the bulb can add an additional 3 to 4 inches (about six inches total) to most Circular, Large, Small, or Straight bulb horns including Dobani product codes BULL, BULS, BULH, BULD, and BULO. Spare brass reed available separately if needed. IMPORTANT: Reed screws into horn, not the bulb. So if your reed screws into bulb, then our bulb will not work. (Yes, the reed slides inside bulb tube. But reed is physically attached to horn). WHY CHOOSE THIS BULB: If you want a brand new pre-tested budget-priced, antique-style, replacement bulb that fits double bell horns and also extends the length of most Circular, Large, Small and Straight bulb horns, then this bulb is for you. TECHNICAL SPECS: Bulb Diameter: 3-3/4" (9.5 cm), Bulb Circumference: 11-1/2" (29.2 cm), Bulb Length to end of brass collar: 5-1/4" (13.3 cm), Brass Tube Length: 5-5/8" (14.3 cm) (more or less), Brass Tube ID (screw fitting): 5/8" (15.9 mm) at 28 tpi (threads per inch), Brass Tube OD: 11/16" (17.5 mm), Three-part Construction: Rubber bulb, brass collar, threaded brass tube, Weight: 6.2 oz (176 g).
