A wheel channel guide-lock assembly for laterally, vertically and horizontally securing adjacent telescoping wheel channels of a bleacher system. The assembly comprises a first type of bracket attached in pairs on one wheel channel which include axles extending therefrom for replacing existing channel wheel axles at opposite ends of a wheel channel. A second type bracket slidingly engages along a rod extending between the said first type brackets of the channel and is attached to an adjacent wheel channel whereby sequentially, adjacent channels are guided and locked together by means of the first brackets preventing the second bracket from sliding therepast.
