| About EL(LL) Series Leaf Chain<\/font><\/b><\/span><\/h2>\n

EL (LL) series leaf chains made to ISO standards are constructed of plates and pin diameter similar to <\/font>British standard roller chains<\/font><\/a> of same pitch. <\/font><\/span><\/font><\/p>\n

For example, EL6 (LL12) uses plates and pin diameter of BS 12B roller chain. <\/span><\/font><\/p>\n

EL leaf chains are commonly used for lightweight load equipment and light lifting applications.<\/font><\/span><\/p>\n

For corrosive environment, <\/font>CRF corrosion resistant coating<\/font><\/a> is available.<\/font><\/font><\/span><\/p>\n


<\/font><\/p>\n

For heavy duty applications, <\/font>BL series leaf chains<\/font><\/a> are recommended.<\/font><\/span>
