A mounting member for a surgical stapler, comprising: a body defining a longitudinal axis ("X2"), the body including: a proximal end portion having a pair of vertical projections (212a, 212b) configured to be coupled to a proximal body portion of a loading unit of a surgical stapler; and a distal end portion including: a pair of walls (222a, 222b) in parallel relationship with one another and extending distally from the proximal end portion; characterised in that the body is fabricated from a plastic and in that the distal end portion includes: a boss (224a, 224b) coupled to, and extending perpendicularly from, one wall of the pair of walls and defining a bore (226a, 226b) therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit; and a strut (228a, 228b) extending from the proximal end portion to the boss (224a, 224b). a body defining a longitudinal axis ("X2"), the body including: a proximal end portion having a pair of vertical projections (212a, 212b) configured to be coupled to a proximal body portion of a loading unit of a surgical stapler; and a distal end portion including: a pair of walls (222a, 222b) in parallel relationship with one another and extending distally from the proximal end portion; characterised in that the body is fabricated from a plastic and in that the distal end portion includes: a boss (224a, 224b) coupled to, and extending perpendicularly from, one wall of the pair of walls and defining a bore (226a, 226b) therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit; and a strut (228a, 228b) extending from the proximal end portion to the boss (224a, 224b). a proximal end portion having a pair of vertical projections (212a, 212b) configured to be coupled to a proximal body portion of a loading unit of a surgical stapler; and a distal end portion including: a pair of walls (222a, 222b) in parallel relationship with one another and extending distally from the proximal end portion; characterised in that the body is fabricated from a plastic and in that the distal end portion includes: a boss (224a, 224b) coupled to, and extending perpendicularly from, one wall of the pair of walls and defining a bore (226a, 226b) therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit; and a strut (228a, 228b) extending from the proximal end portion to the boss (224a, 224b). a pair of walls (222a, 222b) in parallel relationship with one another and extending distally from the proximal end portion; characterised in that the body is fabricated from a plastic and in that the distal end portion includes: a boss (224a, 224b) coupled to, and extending perpendicularly from, one wall of the pair of walls and defining a bore (226a, 226b) therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit; and a strut (228a, 228b) extending from the proximal end portion to the boss (224a, 224b). a boss (224a, 224b) coupled to, and extending perpendicularly from, one wall of the pair of walls and defining a bore (226a, 226b) therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit; and a strut (228a, 228b) extending from the proximal end portion to the boss (224a, 224b).
