Frequently Asked Questions
- What does a strike shield do?
A strike shield is a hardened plate fitted over the latch area of the door frame. On open-out doors, it reduces the gap between the door and frame that can be exploited by shimming or latch-slipping tools, helping to prevent forced entry through latch attack. - Why does this model have a rose cut-out?
Entrance sets such as knob or lever locksets have a rose (a circular backing plate) that sits on the door face. The BOSS087SS includes a pre-formed cut-out to allow the rose to pass through the blocker plate without requiring modification to the plate or the lockset. - What is the difference between visible and concealed fixing?
Visible fix versions such as the BOSS087SS use standard hex bolts that are visible on the door face once installed. Concealed fix versions use hex key bolts that are not accessible from the exterior face, providing a more tamper-resistant installation where that is required. - Is this product suitable for inward-opening doors?
No. The BOSS087SS is specifically designed for open-out doors. Door swing must be confirmed before specifying this product. - Is this strike shield fire rated?
Yes. The BOSS087SS is fire rated and suitable for use on fire-rated door assemblies.
Additional Information
- Strike shields are commonly specified on outward-opening commercial and institutional doors to reduce the risk of latch attack.
- The lockset rose cut-out is a key differentiator of the BOSS087SS, making it suited to doors where the lockset rose cannot be removed or where the entrance set is already installed.
- Grade 316 stainless steel offers superior corrosion resistance compared to grade 304, making it suitable for coastal or high-humidity environments.
- Always confirm the latch position and rose diameter before installation to ensure the cut-out aligns correctly with the installed lockset.
- Supplied in a bulk pack. Confirm pack quantity with supplier at time of order.
