9. The clamp assembly of claim 1 , wherein:

the slot stop is a primary slot stop; and

each of the first clamp sidewall and the second clamp sidewall define a secondary slot stop extending towards the rear clamp wall and at least partially traversing the slot.

10. The clamp assembly of claim 9 , wherein each secondary slot stop is formed as a stop hook at a bottom wall end of the first clamp sidewall or the second clamp sidewall.

11. The clamp assembly of claim 1 , further comprising a clamp end cap mounted to the clamp body at an upper clamp end of the clamp body.

12. The clamp assembly of claim 1 , wherein the slot stop is vertically offset from the post fastener.

13. A reinforcement post assembly comprising:

a fall protection reinforcement post defining a front post side and a rear post side; and

a clamp assembly comprising:

a clamp body;

a post fastener engaging the clamp body and the reinforcement post to secure the clamp assembly to the reinforcement post; and

a clamp spring biasing the clamp assembly to an untightened configuration; and

wherein:

a slot is defined between the clamp body and the front post side of the reinforcement post, the slot configured to receive a guardrail therethrough;

the clamp body defines a front clamp wall confronting the front post side and a rear clamp wall opposite the front clamp wall and confronting the rear post side;

the clamp spring is arranged within the slot between the front clamp wall and the front post side; and

the clamp spring is a button spring clip comprising a substantially inverted V-shaped resilient spring portion and a button tab extending from the substantially inverted V-shaped resilient spring portion.

14. The reinforcement post assembly of claim 13 , further comprising a slot stop engaging the clamp body and traversing a bottom slot end of the slot, the slot stop configured to prevent the guardrail from disengaging the slot at the bottom slot end.

15. The reinforcement post assembly of claim 14 , wherein:

the slot stop comprises a first threaded bolt fastener comprising a threaded shaft;

the threaded shaft of the first threaded bolt fastener engages the threaded fastener bore of the first nut.

16. The reinforcement post assembly of claim 15 , wherein:

the post fastener comprises a second threaded bolt fastener comprising a threaded shaft;

a second nut defining a threaded fastener bore is mounted to the reinforcement post at the rear post side; and

the threaded shaft of the second threaded bolt fastener engages the threaded fastener bore of the second nut.

17. The reinforcement post assembly of claim 16 , wherein the slot stop is vertically offset from the post fastener.

18. The reinforcement post assembly of claim 13 , wherein:
