Normally the LM block and LM rail is a set delivered after action adjustment/verification is complete. Thus when purchasing only the LM block, please send the LM Guide set (LM block + LM rail) or LM rail to be used with the purchasing LM block. After adjusting the action with the sent LM Guide set or LM rail we will deliver the purchased LM block with your sent items.
We understand that it may not be possible to send the LM Guide set or LM rail to be used with the purchasing LM Block though in such cases we still can respond. Please contact THK.
