An apparatus includes a block comprising a lubricant-impregnated material. The block includes a first portion including a first surface having a first groove extending a length of the first surface; and a second portion including a second surface having a second groove extending a length of the second surface. The apparatus includes a shell configured to at least partially enclose the first and second portions of the block and urge the first surface of the first portion into interfacing contact with the second surface of the second portion to form a channel defined by the first and second grooves, the channel configured to receive at least a portion of a chain in contact with the first and second portions of the block to transfer lubricant from the block to the chain through movement of the chain through the channel in contact with the first and second portions of the block.
