The Rk Crawler MD 55 crankbait was designed by MLF Angler Mike McClelland. The RkCrawler MD 55 features all the benefits of the RkCrawler 55. With a shallower dive angle, this bait will be able to come through rock s more like a square bill crankbait to deflect off cover and draw more strikes. When the fish are shallower then 7 feet, the RkCrawler MD should be your go-to RkCrawler. Product Specifications Weight : 1/2 oz. Size : 55 mm Depth : 4-8 ft.
