The damper includes a damper housing and a piston assembly reciprocating therein. The damper housing includes an attachment device formed of an interior partially circular wall with a triangular cross section thereby forming an interior partially circular apex for engaging a cylindrical boss. This allows the damper to rotate about an axis of the interior partially circular wall and pivot about an axis perpendicular to the rotational axis. Additionally, the piston assembly includes a detent protrusion formed from a stem supporting a head, the radius of the head being greater than that of the stem. The detent protrusion is engaged by a keyhole-shaped aperture with a first portion with a radius of curvature substantially equal to that of the stem and a second portion with a radius of curvature substantially equal to that of the head. The detent protrusion can therefore rotate within the keyhole-shaped aperture. Additionally, the cap of the damper housing is formed of elastic O-rings to allow the piston assembly to rotate within the damper housing.
