Small Upgrades, Major BenefitsAt Top Lock Installations, we don't just provide windows; we ensure they are as secure and safe as possible. Our range of accessories is designed to complement our high-performance window systems, offering you peace of mind and enhanced functionality.
Sash Jammers
Sash jammers are small but highly effective security add-ons designed to reinforce uPVC windows and doors. They work by creating an additional locking point that prevents the sash from being forced open — even if the main lock is compromised.
Why They Matter
- Stops forced entry attempts
- Ideal for older frames
- Quick, low-cost upgrade
- Simple swing-arm operation
Types Available
- Standard sash jammers
- Lockable sash jammers (with key)
