Portals Plus 14100 *Clearance* Round Adapter for 2-1/2 in. OD

The Portals Plus Round Adapter for 2 ½″ OD (Item #: POR-14100) is a retrofit component used to adapt round roof penetrations approximately 2.5 inches outer diameter into a compatible retrofit flashing boot. It is installed by fitting around the projection, seating into the correct step of the boot (boot not included), and tightening a clamp (not included) to achieve a watertight seal. This approach lets installers handle non-standard penetrations without full custom boot fabrication.

Key features:

• Adapts roofs with approximately 2 ½″ outer diameter penetrations into compatible retrofit boots.
• Enables reuse of existing stepped flashing boots instead of custom engineered boots.
• Streamlines installation: seat adapter around penetration, fit into boot, then secure with clamp.
• Adapter itself packaged separately; flashing boot and clamp must be purchased individually.

• SKU: POR-14100
• Product type: Round Adapter for 2 ½″ outer diameter penetration
• Intended use: Fits around the penetration; seats into retrofit boot (boot not included)
• Components included: Adapter only; clamp and boot sold separately
• Application: For roof penetration sizes that do not match standard boot sizes and require adaptation

Q: What penetration size does this adapter fit?
A: It accommodates approximately a 2 ½″ outer diameter penetration.

Q: Are the boot and clamp included with this adapter?
A: No. The flashing boot and clamp are sold separately and required for full installation.

Q: Why use this adapter instead of custom flashing?
A: It enables adaptation of non-standard penetrations into standard retrofit boots, reducing the need for custom manufactured boots.

Q: How is the watertight seal created once installed?
A: After inserting the adapter into the boot step, a clamp (not included) is tightened over the assembly to secure a compression seal around the penetration.
