Abstract: A slide-top tent retrofit system for converting a frame tent to a slide-top tent is described. In some embodiments, the system comprises a retrofit end crown fitting that can attach to an original crown fitting using an original attachment means. In some embodiments this retrofit end crown fitting comprises a sliding channel and attaches to retrofit rafter beams, also comprising a sliding channel, which replace original rafter beams. The retrofit rafter beams can also attach to retrofit side eave fittings, which replace original side eave fittings. In larger tents comprising one or more original mid crown fittings, retrofit mid crown fittings can replace the original fittings and attach to retrofit rafter beams. In one embodiment, the retrofit end crown fitting attaches to the original end crown fitting using a pin and hole attachment system.
