Display holders and adapters system

A system for displaying an ESL device, the system comprising:

• a first holder, the first holder comprised of a panel, the panel having a front face and a rear face, the front face configured for engagement to a first ESL device, the rear face having an upper adapter clasping member and a lower adapter clasping member that extend from the rear face of the panel to define a first rear-facing C-channel;
• a first adapter type and a second adapter type, each adapter type having a different shape, each adapter type having a front adapter panel, an upper holder clasping member and a lower holder clasping member extend from a face of the front adapter panel,
• the first adapter type is comprised of the front adapter panel, a top panel and a rear panel, which form a U-shaped grasping channel, the U-shaped grasping channel configured to grasp a retaining bar therein;
• the second adapter type is comprised of the front adapter panel and a surface engagement panel that intersect to form an angle of 120 degrees, the surface engagement panel defining at least one through hole, the at least one through hole adapted to receive a locking pin therethrough;
• the upper holder clasping member of each adapter type comprising a first L-shaped adapter arm, the first L-shaped adapter arm having an upper arm that perpendicularly projects from the face, and a lower arm that perpendicularly projects from an end of the upper arm in a first direction, the front adapter panel, the upper arm and the lower arm of the upper holder clasping member defining an upper U-shaped receiving channel,
• the lower holder clasping member of each adapter type comprising a second L-shaped adapter arm, the second L-shaped adapter arm having an upper arm that perpendicularly projects from the face, and a lower arm that perpendicularly projects from an end of the upper arm in a second direction, the front adapter panel, the upper arm and the lower arm of the lower holder clasping member defining an lower U-shaped receiving channel, the second direction being opposite from the first direction;
• each adapter type being configured for removeable engagement with the first holder, the upper adapter clasping member is constructed and arranged to be slidingly engaged into the upper U-shaped receiving channel and the lower adapter clasping member is constructed and arranged to be slidingly engaged into the lower U-shaped receiving channel.
