The Bug Blocker® Service Door Screen Insert (SDSI)

The Bug Blocker Service Door Screen Insert SDSI


Propped open doors are an invitation to every insect, bird, rodent and unauthorized visitor in the area.

The SDSI represents a new industry standard in screening technology for facilities interested in meeting USDA, FDA, Homeland Security Guidelines or complying with AIB, IPM, ASI and other food inspection requirements. In short anyone interested in Security Ventilation and non-chemical Pest Control for their facility.

The new FSIS Security guideline for food plants states:

“Windows and doors that must be kept open for ventilation are screened to prevent pest entry.”

“Secure doors and access restricted to authorized individuals.”

“Doors, windows and openings should be secured with locks seals and sensors at all times.”

“Emergency exits should be alarmed and have self-locking doors that can only be opened from the inside.”

An entirely new approach to ventilation using a stainless steel mesh screen inserted into an existing hollow metal door. The SDSI meets emergency situation requirements by not interfering with the panic opener and is easily installed into an existing service door. It does this without compromising the strength of your main door nor the ability to be locked from the inside. What makes it unique is that it uses strong 304 stainless steel wire mesh. Used in many prisons and facilities with higher security needs and has been very popular with food processing and packaging facilities do to its ability to keep the bugs out. Security bars can also be added for additional visual security.

When it‘s time to close up for the night or during colder weather there are two choices available: a steel insulated panel or a clear see thru polycarbonate panel. Either one will securely lock into place. A storage rack option can be attached to the bottom of the door or on to the wall to keep the cover panel out of the way and safe from any damage. Our customers tell us they like the SDSI for the ventilation provided, the easy installation, affordability, and that it is a completely legal way to add screening to the door.

Help prevent unauthorized entrance into your facility by people, bugs and birds by using a Service Door Screen Insert. We live in a time of heightened security awareness and requirements. Insert the Service Door Screen Insert (SDSI) and take control of your door security!
