An example holder apparatus includes a body portion and a gate portion. The body portion includes a first sidewall and a second sidewall that opposes the first sidewall to form a channel therebetween. The gate portion is, at least in use, physically coupled to the second sidewall of the body portion and movable between an open configuration and a closed configuration. The gate portion includes a cross-channel member that, when the gate portion is in the closed configuration, extends across an entire width of the channel to physically engage a channel-facing surface of the first sidewall or a portion of an object held between the cross-channel member and the channel-facing surface of the first sidewall. An example kit for a holder apparatus includes a body portion and a gate portion. The gate portion is selectively physically coupelable to the body portion via a snap fit.
