The hinge has a first leaf 20, a second leaf 30 and a pin 40. The first leaf 20 is attachable to a screen door hinge stile 80 and the second leaf 30 is attachable to a door jamb 90. The hinge 10 has an open position and a closed position. 30          The first leaf 20 has a first leaf plate 22. The first leaf plate 22 has a front side 23 and a back side 24. The first leaf 20 has a protruding portion 26 extending from the back side 24 of the first leaf plate 22. The first leaf plate 22 has two holes 28 configured to receive fasteners. 2025201956   18 Mar 2025 The protruding portion 26 has two recesses 27. The second leaf 30 has a second leaf plate 32. The second leaf plate 22 has three holes 31 configured to receive fasteners. The second leaf 30 has two pivot members 34. Each pivot member 34 has a 5 proximal end 35 attached to the second leaf plate 22 and a distal portion 36 spaced from the proximal end 35. Each of the one or more pivot members 34 is integrally formed with the second leaf 30. Each recess 27 is configured to receive the distal portion 36 of one of the pivot members 34. 10         Each pivot member 34 has a bend of approximately 90-degrees. Each pivot member 34 has a first portion 37 and a second portion 38. Each first portion 37 including the corresponding proximal end 35. Each second portion 38 including the corresponding distal portion 36. Each first portion 37 extends perpendicular to the second leaf plate 32. Each second portion 38 extends 15 perpendicular from the corresponding first portion 37. The distal portion 36 is substantially cylindrical. Each recess 27 has a curved portion 29 within which the substantially cylindrical portion of the corresponding pivot member 34 is adjacent when the pivot member 34 received within the recess 27. Each pivot member 34 has a hole in the second portion 38 substantially in the 20 centre of the distal portion 36. Each hole is adapted to receive the pin 40. Each hole defines a substantially central point. The second leaf plate 32 has a front side 33 and a back side. Each pivot member extends from the front side 33. The second leaf plate 32 has a curved longitudinal recess 39 in the front side 33. 25          The first leaf 20 and the second leaf 30 are pivotally connected by the pin 40. The pin 40 is retained by end caps 50A,50B located at either end of the pin 40. The second leaf 40 is rotatable relative to the first leaf 30 about an axis of rotation. The axis of rotation is located within the distal portions 36 of each pivot member 34. In particular, the axis of rotation is coincident with each substantially 30 central point of each of the holes of the distal portions 36. The axis of rotation passes through the recesses 27. The axis of rotation is offset from the first leaf plate 22. In this arrangement the connection between the first leaf 10 and the second leaf 30 is also offset from the first leaf plate 22. Therefore, the connection between the 2025201956   18 Mar 2025 first leaf 10 and the second leaf 30 is not exposed when the hinge 10 is in the open position, the closed position or in between the open position and the closed position. When the hinge 10 is in the closed position the front side 23 faces the front side 33. 5         With reference to Figures 6 to 8, there is shown a frame assembly with the screen door hinge stile 80 being pivotally attached to the door jamb 90 by the hinge 10. The screen door hinge stile 80 has an open position 80A and a closed position 80B. The first leaf 20 is attachable to the screen door hinge stile 80 by at least one 10 screw fasteners 70. The second leaf 30 is attachable to the door jamb 90 by a plurality of fasteners 72. The screen door hinge stile 80 has a recess 84 configured to receive the protruding portion 26. The screen door hinge stile 80 has two holes configured to receive fasteners 15   70. The door jamb has three holes configured to receive fasteners 72. The first leaf 20 is attached to the screen door hinge stile 80 by the fasteners 70. The second leaf 30 is attached to the door jamb 90 by the fasteners 72. The screen door hinge stile 80 has a wall portion 88 which extends to partially cover an edge the first leaf plate 22. 20          When the screen door hinge stile 80 is in the closed position and pivots between the open position 80A and the closed position 80B the longitudinal recess 39 is able to receive the wall portion 88 to prevent the wall portion 88 from contacting the second leaf 30. 25                         ADVANTAGES An advantage of the preferred embodiment of the hinge includes that when installed to a first surface and a second surface, the extent to which the hinge is exposed is minimal. Further, the hinge does not expose the connection between the first leaf and the second leaf (i.e., the hinge knuckle). 30 VARIATIONS While the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be 2025201956   18 Mar 2025 apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth. Throughout the description and claims of this specification the word “comprise” and variations of that word such as “comprises” and “comprising”, are not 5 intended to exclude other additives, components, integers or steps.
