@RichqrddeNooy@mastodon.social The three varieties of vlizotrap: ladder is one piece, but it slides forwards & backwards in brackets on the hatch, precariously changing the balance of opening/closing; ladder is in multiple telescoping sections, with kutknopjes; ladder is in zig-zag folding sections, with added pinching hazards as well as the entire thing thundering down. Come to think of it, that last part is intrinsic in all vlizotrappen.
