The universal Pull-up Bar/Push-up sticks is an easy-to-use and a very good quality model that will be of great assistance to you in your architectural renering. The model has defining edge loops for good subdivision with retaining form, and also is UV-unwrapped with no overlaps per single model.
Modelled to scale.
Looks very good in close-up renders.
The model itself is also relatively low-poly, which allows for game-usage or other real-time software.
