Height adjustment mechanism for a manhole assembly and manhole assembly comprising the same
There is accordingly provided a height adjustment mechanism for a manhole assembly according to one aspect. The height assembly mechanism includes an annular lower body having a threaded interior bore. The height assembly mechanism includes an annular insert threadably engageable with the lower body. The height assembly mechanism includes an annular upper body threadably engageable with and extending outwards from the lower body. Abutting of the upper body with the insert fixes positioning of the upper body.There is also provided a height adjustment mechanism for a manhole assembly according to another aspect. The height assembly mechanism includes an annular lower body having a threaded interior bore. The height assembly mechanism includes an annular upper body threadably engageable with and extending outwards from the lower body. The annular upper body includes a plurality of circumferentially spaced-apart, radially inwardly-extending protrusions.
