Extension cord under-door pass-thru protector

pinshape

The pass-thru protector boasts a unique channel designed specifically to accommodate a flat-style 3-conductor extension cord, such as the Woods Tri-Way Cord available at Target for $10.50. This specialized feature ensures safe and secure passage of the cord through doorways without risking damage from pinching between the door and jamb. To utilize this innovative protector, simply download and print the provided STL file. Next, insert the cord into the channel, taking note that the "inside" section features a slightly angled design to help route the cable away from the doorway when fully opened. Place the protector in the desired location, optionally securing it to the floor using double-sided tape if needed; however, a firm hold is usually achieved without additional support.
