Selens 3Pcs Tripod Foot Long Spikes Stainless Steel Compatible 1/4" Universal for Tripod Monopod Leg Shooting Photography Accessories Equipment Mount Adapter

Seems these are the only long spikes available and the wrong thread size for benro tripods.Should just sell them im 1/4 and 3/8s version.Long spikes in the ground make a huge difference to tripod stability resulting in sharper photos.Managed to screw into benro by another purchase of 1/4 to 3/8s screw adaptors, but this should not be necessary

Bought these for a 3 legged thing tripod, as an alternative to the OEM ones that were 3 times the price. Fit nicely, and good quality too.

Only used these with my tripod a couple of times, both on grassy ground and they worked a treat. Easy to push into softish ground. May be too thin for sand, time will tell. Seem good quality

Well made, solid and made to do the job.

Heavy duty 1/4qtr inch spikes which fit very well, and will make my tripod even more stable in soft ground, or sand.
