𝟑. 𝐅𝐥𝐚𝐭 𝐂𝐡𝐚𝐢𝐧: This curb has the same features as the flat leather curb, with small buckles placed close to the chain, as to not interfere with the cheeks of the bit. The chain lays flat on the lower jaw, in order to conform to the area, and is one step up from the flat leather curb. This curb is available in the 3 ½” and 4 ½”, or longer if needed for specific bits.
