This large tray is ideal for holding small parts and tools. It features deep sides so small items stay put. A variety of slots and holes hold any tool. Tools not included.The 104 is intend for stands with a vertical upright tube. If the 104 tray is fitted to tubes of the tilted PCS-9 and PCS-10 stands, the tray will sit at a slight angle. The 104 tray uses a shim to fit tubes of 1-1/2 (38mm). Without the shim it will fit tubes 1-5/8 (41mm).The 104 tray will NOTfit PRS-2 OS, PRS-3 OS, and PRS-4 OS, PCS-9, PCS-10, PCS-11, PRS-25 and PRS-15. The PRS-5 stands using a black vertical tube mates well with the 104 tray. Pre-2002 PRS-5 models use a blue oval vertical tubing. This blue tubing has marginal but adequate contact with the 104 tray.
