The 1SKB19-R1010 Roto GigRig has set the standard for many years. The roto molded design includes 10U of angled space on the top for mixers and 10U of vertical rack space for outboard effects and amps. The top, front and back lids lock securely together for safe transport while the four casters lock both caster roll and caster swivel. The 1SKB19-R1010V Roto GigRig shares all of the same specifications but adds a completely adjustable pop-up hook and loop fastener board on top to accommodate a wide variety of smaller mixers and or accessories.
