Noch Locomotive Servicing Cradles have two hollows for your locomotives; one for placing the engines upside down (perfect for working on underbodies and gearing) and the other for working on equipment on an angle. Soft foam holds equipment securely without damage. The cradles have different compartments and recesses to hold brushes, oiling pens and tools. Small parts and screws can be stored in the integrated compartments while you work. So that small parts do not get lost, a magnetic disc is incorporated in one compartment of the servicing cradle - perfect for retaining tiny screws and other steel parts. The large servicing cradle is designed to hold HO and TT Scale equipment and measures 11-13/16 x 8-1/4 x 2-3/16" 30 x 21 x 5.5cm. The small cradle measures 7-7/8 x 6-7/8 x 1-9/16" 20 x 17.5 x 4cm for N and Z Scale models.
