a curved tip at an end of each arm opposite the bottom portion; and wherein the arms include the wings in between the bottom portion and the curved tip.

11. A strut receiver as in claim 10 , wherein the wings include sheer tabs to snap into a rim on the slotted structural member and wherein the arms engage a rim edge on the slotted structural member.

12. A strut receiver assembly for springing attachment to a slotted structural member comprising:

a strut receiver;

a bottom portion having a plurality of slots;

a first side connected to the bottom portion, the first side including a first inwardly curved tip opposite the bottom portion;

a second side connected to the bottom portion, thereby forming a U-shaped structure with the first and second sides, the second side including a second inwardly curved tip opposite the bottom portion, such that the first and second inwardly curved tips curve toward each other;

a plurality of first engagement springs each having an outward facing wing on the first side operable for springing attachment to a first rim on the slotted structural member;

a plurality of second engagement springs each having an outward facing wing on the second side operable for springing attachment to a second rim on the slotted structural member;

wherein each outward facing wing has an open end opposite the inwardly curved tips, and further includes a depression having a thickness less than a thickness of each outward facing wing; and

a band having a bottom portion, a first side having a first arm for engaging a first receiver slot of the plurality of slots and a second side having a second arm for engaging a second receiver slot of the plurality of slots.

13. A strut receiver assembly as in claim 12 , further comprising:

a wing extending from the arms;

a knuckle on each wing to snap the wings into the receiver slots.

14. A strut receiver assembly as in claim 13 , further comprising a depression on each knuckle to allow for low insertion force and a relatively high extraction force when engaging the receiver slots.

15. A strut receiver assembly as in claim 13 , wherein the band further comprises a servicing tab on each wing for removably retaining the band into the receiver slots.

16. A strut receiver assembly as in claim 12 , wherein the band bottom portion further comprises a plurality of tensioner prongs to engage a conduit when the band is in an engaged position with the receiver.

17. A strut receiver assembly as in claim 12 , wherein each arm on the band has a tapered flange.

18. A strut receiver assembly as in claim 12 , wherein each arm on the band has a shoulder stop.

19. A strut receiver assembly as in claim 12 , wherein each arm on the band has a curved tip at the end of the arm.

20. A strut receiver assembly as in claim 12 , wherein the band further includes at least one insertion tab.

21. A strut receiver assembly as in claim 12 , wherein the wings further comprises at least one first side engagement region and the second side further comprises at least one second side engagement region.

22. A strut receiver assembly as in claim 21 , wherein the depression is stamped to form a width.

23. A strut receiver assembly for springing attachment to a slotted structural member comprising:

a strut receiver;

a bottom portion having a plurality of slots;

a first side connected to the bottom portion;

a second side connected to the bottom portion, thereby forming a U-shaped structure with the first and second sides;
