| Ventilation Blocks |
| Sometimes ventilation may be needed in a wall, this block provides that. We provide a mesh grill for the inside face of the block to stop creepy spiders sneaking in for a sleep at night. This block only really goes with the clear frosted block. Can look out of place in the middle of a nice coloured wall. |
