Can all glass doors be fitted with hole-free locks?

Published On : Thursday, September 17, 2026

It's not. "No punch" is not the same as "all-purpose". Generally, the following requirements shall be met at the same time:

  • glass is tempered glass or laminated glass, thickness in 8-12mm interval (10-12mm is the most common), the thickness error of more than 1mm may not be tightly clamped or stuck;
  • between the two doors door seam not less than 6mm to ensure the normal occlusion of the lock tongue;
  • Clamping locks are not recommended for ordinary float glass, glass with baking varnish or film (film may blister due to pressure).
