Abstract: A suction cup headphone apparatus capable of enclosing an ear of a user by way of suction and delivering audible sound. The apparatus comprises a suction cup, a loudspeaker unit, and a housing unit. The suction cup is mounted to the housing unit. The loudspeaker unit is mounted inside the suction cup. The apparatus is placed over the ear. The user applies repeated pressure to the distal end of the suction cup. This forces air out of the suction cup, creating a suction seal between the apparatus and the ear and/or head of the user. The suction seal can keep the apparatus on the user's ear without the necessity of a band until the user removes the apparatus.

Abstract: Disclosed herein is a modular safety rail and system for a flatbed platform, comprising first and second end post assemblies defining first and second ends of the safety rail; at least one intermediate post, each intermediate post comprising a first cable holder and a second cable holder; a cable configured to connect with the first end post assembly and the second end post assembly and configured to be removably positioned within and pass through the first cable holder and second cable holder of each intermediate post; and a cable winch connected to a first end of the cable and configured to spool and unspool the cable. Also disclosed herein are kits and methods for using the disclosed safety rail and system.
