The enclosure consists of a small L-shaped piece floor-to-ceiling and a door. Either Timeless' measuring was incorrect or the glass cutting, I don't know, but the resulting tolerance for the door closure was about 1 mm., if that. On two occasions in the past I have made adjustments with difficulty, having called Timeless and received no reply. Now, I am unable to make any adjustment to allow it to close properly (using the hex Allen key in the hinge bolts). I have two other similar enclosures done by two other companies both of which work perfectly and have never needed adjustment. I have called the company again - they don't answer their phone or return messages asking for help. Avoid this company.
