A wear member attachment system for use with an excavation implement can include a connector that releasably secures a wear member to the excavation implement, the connector including an elongated housing and engagement members extendable and retractable relative to the housing. One engagement member can extend relative to the housing when another engagement member retracts relative to the housing, and vice versa. A method of releasably securing a wear member to an excavation implement can include rotating a engagement member of a connector from an extended position in which opposing slots in the engagement member are aligned with respective projections in the wear member, to a retracted position in which the slots are not aligned with the projections. The rotating step can include extending another engagement member of the connector as the first connector displaces from the extended position to the retracted position.
