Johnson Hardware’s Trackless Door Guides eliminate the need for a threshold or bottom guide track for bypass doors. The 100MP, 111MP, 100BP, and 111BP models feature a top precision extruded aluminum “jump-proof” box track for doors up to 200 pounds in three thicknesses: 1 3/8, 1 3/4, or 2 1/4 inches. Pricing varies. The 100MP costs $199. johnsonhardware.com
