The GE Zoneline 42″ Quick Snap Wall Sleeve, Insulated (RAB42MG) is a heavy-duty through-the-wall mounting sleeve designed specifically for GE Zoneline PTAC units. It serves as the structural housing that your air conditioner slides into and anchors securely within an exterior wall opening. The insulated construction helps reduce energy loss, improves overall comfort, and protects the air conditioner from outdoor moisture and drafts.
