Teris TS-S45 Mid-Level Spreader

A mid-level spreader braces the legs partway up rather than at the feet, which is what you want on uneven ground, on stairs, or anywhere a ground spreader has nothing flat to sit on. The TS-S45 sets a 290 to 460 mm build radius and locks the three legs against each other at that height.

Teris lists it for the TS1610AL, TS1610CF, TS1610CF-Q, TS2210CF, and TS2215CF tripods. It weighs 0.76 kg, so it is reasonable to leave fitted rather than swapping spreaders between locations.
