The Triple E Loose Pin Hinge is the original loose pin hinge and still has the most features out of any on the market:
A large diameter pin with tapered end and sturdy ‘knock-in/knock-out’ head
A central square hole for a coach bolt
Offset screw holes to prevent timber splitting
Vee notches on four sides align with the central hole, allowing the hinge to be folded around an edge
Centre line markings allow the hinge to be accurately positioned over a line
The two halves have a built-in tolerance to allow for any discrepancies
