An apparatus for securing a caster to an object having a hole with interior walls has a tubular body with upper and lower ends, the lower end being adapted to connect to a caster and the upper end being split and defining at least two upwardly extending friction grip arms, the upper end of each arm defining an outwardly extending friction grip portion and the outer dimension defined by all of the friction grip portions being slightly larger than the minimum corresponding dimension of the hole.

An apparatus for securing a caster to an object having a hole with parallel interior walls and a constant, minimum interior width along the height of the apparatus for securing the caster, comprising: a tubular body having upper and lower ends, the lower end having connection means for connecting to a caster and the upper end being split and defining at least two upwardly extending friction grip arms, and wherein the lower end has an external cross-sectional width which is substantially equal to the interior width of the hole to provide lateral stability of said tubular body within the hole; a caster having an upward stem accurable to said means for connecting within the lower end of the tubular body; wherein the friction grip arms project radially outward beyond the external cross-sectional width of the lower end when the tubular body is outside of the hole, and wherein upon axial insertion of the tubular body into the hole the interior walls of the hole bear against the friction grip arms and urge them radially inward, providing a friction fit between the friction grip arms and the interior walls; and wherein an interior diameter of the upper end of the tubular body is greater than an outer diameter of the caster stem to allow the friction arms to deflect radially inwardly without obstruction by the stem.
