Two Knuckle Lift Off Hinges (H100 Series)
Two knuckle lift off hinges are primarily designed for off-site doorset manufacture whereby the doors and frames can be prepped at works and the doors are subsequently just dropped into place on site (where headroom allows). Lift off hinges are also useful where door have to be frequently removed although care should be taken not to bend the pins when doing so.
HI-LOAD lift off hinges as part of the HI-LOAD range also account for both vertical load and side load as part of their design although they generally suffer from reduced weight loading than their three knuckle equivalents.
