The K 70 has a profile of 4.5 x 7.0 cm. We use seasoned and kiln-dried pine for the stretcher frame. The wood is finger-jointed to prevent the natural tendency of the wood to warp and, thanks to multiple gluing, is almost free of warping- a high-quality handcrafted product at an extraordinarily affordable price.

The stretcher frame is available from a side length of 30 to 500 cm. We will be happy to cut the frame to your desired format for an additional charge of 5 euros per bar. Please note that the cross bars must also be cut to size.

The stretcher frame has a sharp edge as standard.

In order to obtain a stretcher frame, you need two stretcher bars of the long side, two of the shorter side and optionally a middle piece or cross and wedges.

The hard wood wedges necessary for wedging (2 pieces per bar and middle bar) are not included in the price. Please order for the stretcher bars and the cross braces https://peters-art.de/en/painting-supports/stretchers/wooden-stretchers/918/wedges-big-k70/keys-50pcs.?number=10872

If you require an additional bracing, please combine the frame with the cross bars K70: https://peters-art.de/en/painting-supports/stretchers/wooden-stretchers/17/cross-brace-for-k70-and-k6570-7-0x4-5cm?number=10017

The stretcher frame has a 1-fold slit from a side length of 50 cm up to a side length of 195 cm, a 2-fold slit from a side length of 200 cm, a 3-fold slit with a side length of 300 cm and a 4-fold slit from a side length of 400 cm.

Advice on bracing:
Under a side length of 1m no middle bars are needed. If one side length exceeds 1m, one middle bar of the shorter side length is sufficient.If both sides are more than 1m long, you need one bar per side length (a simple cross). If one side is more than 2m long, you need two middle pieces of the shorter side and one of the long side (single double cross). If both sides are more than 2m long, the stretcher bars are each double slotted, so you need two middle bars per side length (double double cross). With this profile, bars are triple slotted over 3m length and quadruple slotted over 4m length. Please select the appropriate number of middle pieces.
