# Layout the Door and Clamping Plates

**Step 1: Mark out the location of the door kit. **

Starting from a marked setout point:

- Mark a line at the distance of the setback (dimension “F” on the [82280 DD BayDrive Sales Drawing](https://bit.ly/3qoPvKg)) from the setout point to a setback point.
- Mark a line for the centre of the culvert.
- Mark a line for the centre of the rubber door.

**Step 2: Lay out and align the rubber door**

Lay the rubber door inside the culvert. 

- The upstream edge of the rubber door should align with the setback point.
- The centre of the rubber door should align with the canal floor centreline.

**Step 3: Lay out the clamping plates**

- Insert clamping plates over the rubber door. Ensure that the holes of the clamping plates align with the holes in the rubber door.
- Ensure the rubber door follows the contour of the canal floor and batter slope.

# Drill Holes and Install Anchors

**Step 1 Drill the anchor holes**

Mark the hole locations for all anchors. Apply a gentle downward pressure on the vertical member of the front clamping plate to ensure the rubber follows the contour of the canal floor and batter slope.

**Step 2 Remove the clamping plates and rubber door and clean the holes**

Lift the rubber door and drill the anchor holes.

**Step 3 Install anchors**

Install all the anchors. 

# Apply Sealant and Secure the Door and Clamping Plates

**Step 1 Apply sealant on the concrete for the clamping plates**

- Apply a bead of polyurethane sealant along the full length of the underside of the rubber door (under the footprint of each of the clamping plates). Apply enough sealant to cover the width of the clamping plates when they are compressed against the culvert.
- Apply a bead of sealant around each anchor and run a bead of sealant along the footprint of each clamping plate on the concrete.

**Step 2 Move the rubber gate and clamping plates into position**

- Move the rubber gate back into position aligning the holes with the matching anchors.
- Move the clamping plates back into place. Apply gentle pressure and tap them into place with a mallet.

**Step 3 Secure the anchors**

Place nuts and washers on the anchors and tighten to the manufacturer’s specifications. (See [https://rubiconwater.atlassian.net/wiki/spaces/BY/pages/2319876123](https://rubiconwater.atlassian.net/wiki/spaces/BY/pages/2319876123)for details)

**Step 4 Seal the upstream edges of the rubber door**

Apply a bead of sealant around the upstream edges of the rubber door and up to the upstream face of the clamping plates. Remove any excess sealant with a gloved finger.
