    [content] => <p>Back check is a function within the door closer that provides resistance to prevent damage if a door leaf is violently thrown open. The back check action can help prevent damage to the door, door frame, walls and door handles that can be caused when a door is kicked or thrown open rapidly.</p>

<p>Back check will cushion and slow the door down when it reaches approximately 90&deg;.  The angle and resistance of the back check can be adjusted by means of a valve located on the front of the door closer unit.</p>

<p>Please Note: The back check facility can put additional strain on the door hinges - it is recommended that fire doors are fitted with 3 hinges, one at the top, one in the middle and one at the bottom.</p>
