The latest edition to the Wheatley range of fly boxes EASY GRIP FOAM INSERTS have been developed so that the fly is gripped in a slit in the foam. This revolutionary method not only holds the fly securely in place, but it also increases the longevity of the foam. Simply place the bend of the hook into the triangle "cut-out" and push the fly up into the slit. To remove, lift the fly directly upwards out of the foam EASY GRIP INSERTS are available in either the "regular" size for small flies, buzzers, etc and the "large" for lures and salmon flies. 1602EG Swing Leaf. 4 surfaces of Easy Grip foam. Size in inches: 6 " x 3 1/2 " x 1 1/8 "
