Our pusher blocks are inter-changeable on both the 300 & 400 Series Machine.
Please be sure to select the size for the machine you already have. Cutting Heads & Pusher Blocks are made specifically to fit individual sizes. For example: If you have a 3/8" Cutting head, you must use the 3/8" Pusher Block, no other size will fit. Using the incorrect size can cause blades to break. To convert or change size to a new size you must purchase a complete cutting head & pusher block.
To determine what size pusher block you need, see the back of the block where the size is molded into the plastic.
