How It Compares
Compared With Padlock eyes and staples
A hasp spreads the fixing over a plate and hides the screws; a simple staple leaves both the screws and the joint exposed.
Use Guide
- Fit the hasp so the staple sits centrally in the slot with the door closed.
- Use a padlock shackle that fills the staple; a thin shackle leaves room for a lever.
