wrist traps generally do not have a problem with the split-ring
coming in contact with the camera body but this not true of all
cameras. I have three types of strap bumpers: the O-Ring Strap Bumper,
the Octagonal Strap Bumper, the Integral Strap Bumper. These are
for use with wrist straps and neck straps that use a split-ring
to attach to a lug mount.
made of the same latigo hide that the straps are made of but they
have been thinned.
Strap Bumper and the Octagonal Strap Bumper can be purchased with
or without a strap but the Integral Strap Bumper can only be purchased
with a strap since it is part of the strap.
