Kinematic durations of proximities, related to the pairs of orbits of the quasicomplanar asteroids, found out earlier, with mutual inclinations not exceeding $0^{\circ}$.500 and minimum mutual distances under 0.0004 AU (60000 km) were determined. These kinematic durations may be useful in providing orientation on how long intervals could be expected during which eventual perturbing effects occur at the found proximities. Angular widths on the orbits, enclosing the proximities, are also determined. For those among the pairs which are particularly outstanding, positions are given of the outermost points of the corresponding sections. Data presented may be of practical interest in the observations of these minor planets.
