A handle set includes an operator having a retention slot. A chassis is provided for mounting the operator. The chassis includes a sleeve having a bore, and an opening extending through the sleeve to the bore. An operator catch cartridge assembly is configured for mounting to the chassis via the opening. The operator catch cartridge assembly includes a housing defining a guide channel. An operator catch is positioned in the guide channel for sliding engagement with the housing. A biasing member biases the operator catch with respect to the housing. The operator catch engages the retention slot in the operator when the operator is received over the sleeve of the chassis.

What is claimed is: 1. A handle set, comprising: an operator having a retention slot; a chassis for mounting said operator, said chassis including a sleeve having a bore, and a first opening extending through said sleeve to said bore; and an operator catch cartridge assembly configured for mounting
What is claimed is: 1. A handle set, comprising: an operator having a retention slot; a chassis for mounting said operator, said chassis including a sleeve having a bore, and a first opening extending through said sleeve to said bore; and an operator catch cartridge assembly configured for mounting to said chassis by insertion of said operator catch cartridge assembly into said first opening, said operator catch cartridge assembly including a housing defining a guide channel, an operator catch positioned in said guide channel for sliding engagement with said housing, and a biasing member for biasing said operator catch with respect to said housing, said operator catch engaging said retention slot in said operator when said operator is received over said sleeve of said chassis, said sleeve of said chassis including a second opening extending through said sleeve to said bore and positioned opposite to said first opening, said operator catch extending from said second opening in said sleeve when said operator catch cartridge assembly is installed in said chassis. 2. The handle set of claim 1, said first opening of said sleeve of said chassis defining a keyway, and said housing of said operator catch cartridge assembly including a key configured to be received in said keyway. 3. The handle set of claim 2, said keyway defining a plurality of key slots and said key defining a corresponding plurality of key members. 4. The handle set of claim 1, said housing of said operator catch cartridge assembly including a retainer to inhibit removal of said operator catch cartridge assembly from said chassis. 5. The handle set of claim 1, said housing being made of plastic. 6. The handle set of claim 1, said sleeve of said chassis including a side wall through which said first opening extends to said bore. 7. The handle set of claim 1, said sleeve of said chassis including a cylindrical wall through which said first opening extends to said bore. 8. A handle set, comprising: an operator having a retention slot; a chassis for mounting said operator, said chassis including a sleeve having a bore, and a first opening extending through said sleeve to said bore; and an operator catch cartridge assembly configured for mounting to said chassis by insertion of said operator catch cartridge assembly into said first opening, said operator catch cartridge assembly including a housing defining a guide channel, an operator catch positioned in said guide channel for sliding engagement with said housing, and a biasing member for biasing said operator catch with respect to said housing, said operator catch engaging said retention slot in said operator when said operator is received over said sleeve of said chassis, said biasing member including a pair of springs, said guide channel defining in said housing a first spring chamber and a second spring chamber, each of said first spring chamber and said second spring chamber respectively receiving one of said pair of springs. 9. The handle set of claim 8, said operator catch including a body having a catch member, a first elongate member and a second elongate member, said first elongate member being received in said first spring chamber and said second elongate member being received in said second spring chamber. 10. A handle set, comprising: an operator having a retention slot; a chassis for mounting said operator, said chassis including a sleeve having a bore, and a first opening extending through said sleeve to said bore; and an operator catch cartridge assembly configured for mounting to said chassis by insertion of said operator catch cartridge assembly into said first opening, said operator catch cartridge assembly including a housing defining a guide channel, an operator catch positioned in said guide channel for sliding engagement with said housing, and a biasing member for biasing said operator catch with respect to said housing, said operator catch engaging said retention slot in said operator when said operator is received over said sleeve of said chassis, said housing of said operator catch cartridge assembly including a keeper formed along said guide channel to retain said operator catch in said guide channel. 11. An operator catch cartridge assembly configured for mounting as a unit to a chassis, said chassis being configured to receive an operator, said operator catch cartridge assembly comprising: a housing defining a guide channel; an operator catch positioned in said guide channel for sliding engagement with said housing; and a biasing member for biasing said operator catch with respect to said housing, said operator catch being configured to engage a retention slot in said operator to retain said operator on said chassis, said housing, said operator catch and said biasing member being assembled as a cartridge assembly, said biasing member including a pair of springs, said guide channel defining in said housing a first spring chamber and a second spring chamber, each of said first spring chamber and said second spring chamber respectively receiving one of said pair of springs. 12. The operator catch cartridge assembly of claim 11, said housing including an external key for engaging a corresponding keyway in said chassis. 13. The operator catch cartridge assembly of claim 11, said housing including a retainer to inhibit removal of said operator catch cartridge assembly from said chassis. 14. The operator catch cartridge assembly of claim 11, said operator catch including a body having a catch member, a first elongate member and a second elongate member, said first elongate member being received in said first spring chamber and said second elongate member being received in said second spring chamber. 15. The operator catch cartridge assembly of claim 11, said housing including a keeper formed along said guide channel to retain said operator catch in said guide channel. 16. The operator catch cartridge assembly of claim 11, said housing being made of plastic. 17. A method of assembling a handle set, comprising the steps of: assembling an operator catch cartridge assembly as a unit, said operator catch cartridge assembly including a housing defining a guide channel, an operator catch positioned in said guide channel for sliding engagement with said housing, and a biasing member for biasing said operator catch with respect to said housing; inserting said operator catch cartridge assembly into a side wall opening in an operator sleeve of a chassis; and sliding a barrel portion of an operator over said operator sleeve, said barrel portion having a retention slot, said operator catch of said operator catch cartridge assembly engaging said retention slot in said operator to retain said operator on said operator sleeve.
